bug#52493: 29.0.50; Setting Inconsolata up in init.el makes default face rendered wrong

[Dmitry Gutov]

It's a weird scenario, but evaluating this in 'emacs -Q' will make
characters render more narrowly (and a little shorter) than it did
previously:

(set-face-attribute 'default nil :height 110 :family "Inconsolata_dz")

See the attached screenshot with comparison (master is on the left).

This seems to happen with both Inconsolata_dz which I use and the
original Inconsolata (at least some version of it). The font file which 
I use
resides is linked to at the bottom of 
https://nodnod.net/posts/inconsolata-dz/.

It started to happen right after the changes required to use the
"proportional mode-line" were added. I was kind of waiting for somebody
else to report this problem. ;-( It makes master fairly unusable to me,
however.

Other fonts don't seem to have this effect.

Also, if I first evaluate this form, and then change the :family value
to "Hack", the font changes once (to a font with "normal" width) but
then no subsequent evaluations of this form with other values have any
effect on the used font-family (it is "stuck"), but the window shrinks a
little every time.

Indeed, weird.  What does the below show?

  M-: (face-font 'default) RET

after you evaluate the above in "emacs -Q"?  And how does it differ
from the same in a version of Emacs that predates the changes of the
mode-line face?

Also, what happens if you invoke Emacs like this:

  $ emacs -Q -fn Inconsolata_dz

"-DAMA-Ubuntu Condensed-regular-normal-normal-*-29-*-*-*-*-0-iso10646-1"

So... not the right family and it's "condensed", for some reason.

For comparison,

(set-face-attribute 'default nil :height 110 :family "Ubuntu")

results in

"-DAMA-Ubuntu-regular-normal-normal-*-29-*-*-*-*-0-iso10646-1"

And by default (without any set-face-attribute calls),

(face-font 'default) evaluates to

"-DAMA-Ubuntu Mono-regular-normal-normal-*-35-*-*-*-m-0-iso10646-1"

> And how does it differ

Current emacs-28 returns

"-PfEd-Inconsolata_dz-normal-normal-normal-*-29-*-*-*-m-0-iso10646-1"

Regarding "version of Emacs that predates", I wasn't sure which commit 
to pick exactly, but 756b8a5f1bd28aeadc804 also returns that value, and 
doesn't have the described problem.

> Also, what happens if you invoke Emacs like this:

It doesn't look as narrow, and (face-font 'default) evaluates to

"-PfEd-Inconsolata_dz-medium-normal-normal-*-32-*-*-*-m-0-iso10646-1"

Thanks.  I think this means that Emacs 29 on master now rejects the
Inconsolata_dz font for some reason, or thinks it finds a better
match.  The fact that it picks a condensed family is probably
secondary; the main issue here is that the font family you requested
is rejected.

Does that family have the regular weight?  If not, maybe that's the
reason it is rejected, and you need to also require some specific
:weight value in your set-face-attribute call.

Also, maybe running

  $ FC_DEBUG=1282 emacs -Q

will give us a clue of what happens.  See

  https://www.freedesktop.org/software/fontconfig/fontconfig-user.html#DEBUG

for where I took that weird value.

Robert, any other ideas?

If this doesn't help, I'm afraid the only way forward is to step
through the code which selects a font when you specify the family for
the default face, and see what happens there and why.

Despite 'emacs -Q -fn Inconsolata_dz' having the intended effect?

Although yes, something to that effect seems to be going on. But 
specifying different values of :weight doesn't help either (regulal, 
medium, light, bold, extra-bold).

Nor :width (condensed/semi-condensed/normal).

Yes.  The -fn argument forces Emacs to use the specified font, whereas
:family is much more general and doesn't force the use of a specific
font.

If playing with :weight didn't help, what other evidence did you see
that this issue is related?

Related to not being able to select that family (as opposed to 
rendering it wrong, for instance).

I also tried different scenarios which seemed to help (choose another 
family, and a different weight, and then this one), but apparently they 
ended up selecting a different family ultimately, rather than the one I 
specified.

I see.

If you can afford it, please try building the master branch at commit
4e9764e.  This is one commit before Lars installed the support for the
'medium' value of :weight, and the question is whether that change
caused what you see.

Thanks.

Hm, but then I don't understand why using ":weight medium" in
set-face-attribute didn't help you to get the font you wanted.  That's
the main change of that commit, AFAIU.

Maybe try to change the weight first and the family after it?

Does that font have a 'regular' weight variety?  If not, I think this
is a variant of the same issue I fixed in bug#51768: we now request a
'regular' weight when a face specifies the family, and a font which
doesn't have 'regular' is rejected.  So maybe the kludge that I added
to font.c only for MS-Windows should be in effect on Posix systems as
well?

I'm not sure how to check. But in the font viewer, in the details,
Inconsolata has "Style: Medium", and Inconsolata_dz has "Style: dz".

Most of the others (including InconsolataLGC) have "Regular" in that field.

There's part of the font_delete_unmatched function that's conditioned
on HAVE_NTGUI.  If you remove the condition (so that the code there is
unconditionally compiled) and rebuild, does the problem go away?

Yup! Seems to help.

This is one additional piece of misbehavior (perhaps unrelated) that 
really caught my eye during these tests:

When I evaluate

   (set-face-attribute 'default nil :height 110 :family "InconsolataLGC")

(this variation of the font doesn't have the original problem), the 
height of the window shrinks, unless the window is maximized.

If I evaluate it multiple times, the height shrinks every time I do that 
(stopping at height 5, when even the minibuffer becomes inaccessible).

If I evaluate

   (set-face-attribute 'default nil :height 110 :family "Inconsolata_dz")

(with your fix applied), it only shrinks twice (from 33 to 29 to 27, as 
reported by (window-height)). And then stops shrinking on subsequent 
attempts.

Doing the same with InconsolataLGC on the latter build still makes it 
shrink indefinitely.

Lars, do we make that kludge unconditionally compiled on all systems?
The change which Dmitry's bisection found as the culprit cannot be
undone, I think, because without it we cannot support medium weight
separately from regular.  The change I made in font.c is the second
best, I think (or at least I couldn't think of a better one) for
people who have long-time setups which worked until now because we
treated medium and regular as the same weight.

The original shrinking is expected, I think, but the subsequent ones
shouldn't happen.  Martin, could you look into this, perhaps?

I installed the change.  Dmitry, please see if the original problem is
indeed fixed.

I will not close the bug anyway, because of the resizing issue that
still needs investigating.

BTW, the original problem is back now. I vaguely recall that we 
installed the fix, but then backed out of it?

Maybe we should register that info in this bug somehow. Call it a wontfix?

Too bad the recent changes by Gregory didn't improve this scenario.

Which scenario?  If I put

(set-face-attribute 'default nil :height 110 :font "Inconsolata_dz")

in a init file, everything works as I'd expect it to work.

Can you show your results and contrast them with what Dmitry reported

Evaluating

(set-face-attribute 'default nil :height 110 :family "Inconsolata_dz")

(note the ":family") has no effect, IOW the font of the default face is 
unchanged.  Evaluating

(set-face-attribute 'default nil :height 110 :font "Inconsolata_dz")

(note the ":font") changes the default font to Inconsolata_dz, and 
(face-font 'default) returns

"-PfEd-Inconsolata_dz-medium-normal-normal-*-29-*-*-*-m-0-iso10646-1"

The result is the same before the change in bug#59347.

With emacs -Q -fn Inconsolata_dz the font of the default face is

"-PfEd-Inconsolata_dz-medium-normal-normal-*-32-*-*-*-m-0-iso10646-1"

The result is the same before the change in bug#59347.

Correct.  But I don't have the Ubuntu Condensed font installed, so it's 
not surprising that this result cannot be reproduced exactly.  It does not 
reproduce approximately either, in the sense that (set-face-attribute 
'default nil :height 110 :family "Inconsolata_dz") does not change the 
font at all, not even temporarily.

Here are a bunch of scenarios, most of them pretty odd. I was primarily 
testing scenario number 2.

1. If I put this in my init file and start Emacs, during startup it 
blinks to a weird font (narrow window, narrow characters), but then 
finishes startup with a window that looks reasonable (both the size of 
the window and the shape of characters). 'M-x describe-face RET default' 
reports "Inconsolata_dz" as family.

2. I start 'emacs -Q' and evaluate (set-face-attribute 'default nil 
:height 105 :family "Inconsolata_dz") in *scratch*. I get that 
weird-looking font that blinks briefly in scenario 1. 'M-x describe-face 
RET default' reports "Ubuntu Condensed" as family.

3. I start from the end of 2. and press 'C-x 5 2'. The new window pops 
up with reasonable-looking font and size. 'M-x describe-face' reports 
"Inconsolata_dz" as family.

4. I start with 'emacs -Q' and evaluate (set-face-attribute 'default nil 
:height 110 :family "Cascadia Mono"). This works fine on the first try 
without splitting frames, 'M-x describe-face' reports "Cascadia Mono". 
Same with "Inconsolata LGC".

5. I start my regular init script with (set-face-attribute 'default nil 
:height 105 :family "Inconsolata LGC") in it. Then in scratch evaluate 
(set-face-attribute 'default nil :height 105 :family "Inconsolata_dz"). 
I get another funny-looking font. 'M-x describe-face' says it's "Purisa".

6. I start with 'emacs -Q' and evaluate (set-face-attribute 'default nil 
:height 110 :family "Cascadia Mono") there. Works as expected. Then I 
evaluate (set-face-attribute 'default nil :height 105 :family 
"Inconsolata_dz") -- the font size changes slightly (downward), but the 
face remains the same. 'M-x describe-face' corroborates that.

I think the problems here are:

- Inconsolata_dz only works in frames created later.
- Setting font attributes may result in unpredictable results, they 
depend on the previous font spec. Even though the explicit attributes 
are all rewritten to new values every time.
- Unknown font families fail silently (switching to something else under 
the hood). Perhaps it was also the case before, but it adds to the 
confusion.

Can you please try an init file with only that line, and that exact line? 
Note that your original recipe used ":family", where ":font" should be 
used (and is used in the call to set-face-attribute above).

Again, can you try to evaluate (set-face-attribute 'default nil :height 
110 :font "Inconsolata_dz") (with ":font", not ":family") instead, and 
tell us what happens?

Can you try your other recipes, using ":font" where you used ":family", 
and tell us whether what happens is what you expected?

What is the significance of using :font instead of :family in these
cases, for the purpose of discussing and investigating this issue?

The two reasons are:

1. IME passing an font name in the :font attribute gives in general better 
results than passing a font name in the :family attribute.  (And Dmitry 
confirmed that the problem he was facing was mostly solved with that 
change.)

2. Dmitry's specific recipe, which worked with Emacs 28, cannot work 
anymore with Emacs 29 because of dae3c4e89b.

It is strange, because if the family is simply the name of the font,
it should be interpreted the same, because what else could family mean
in that case?

In theory, yes, but in practice the code paths are different in both 
cases.  The :font attribute gets a special treatment in 
Finternal_set_lisp_face_attribute, which is more "direct" than the 
treatment of the :family attribute, and (again IME) gives better results.

With :font, the recipe seems to be working fine. Thanks!

I've always used :family for this purpose in the past.

The behavior seems to be as expected: this font is assigned in the 
current frame.

> Can you try your other recipes, using ":font" where you used ":family", 
> and tell us whether what happens is what you expected?

Almost good, with one problem jumping out, however:

- Evaluate (set-face-attribute 'default nil :height 105 :weight 'regular 
:font "Inconsolata LGC"), result:

              Family: Inconsolata LGC
           Foundry: PfEd
             Width: normal
            Height: 105
            Weight: regular

- Then I evaluate (set-face-attribute 'default nil :height 110 :weight 
'semi-light :font "Cascadia Mono"), the result is:

            Family: Inconsolata LGC
           Foundry: PfEd
             Width: normal
            Height: 105
            Weight: regular

Note the weight. Cascadia Code seems to be thicker than average as a 
font, so the weight of the regular font jumps out, and it was easy to 
notice.

If I, however, follow (set-face-attribute 'default nil :height 105 
:weight 'regular :font "Inconsolata LGC") with (set-face-attribute 
'default nil :height 110 :weight 'semi-light :family "Cascadia Mono") -- 
note :family, the resulting font looks fine, and is described as:

            Family: Cascadia Mono
           Foundry: SAJA
             Width: normal
            Height: 109
            Weight: semi-light

Starting the session with (set-face-attribute 'default nil :height 110 
:weight 'semi-light :font "Cascadia Mono") also has this problem.

However, switching from :family to :font -- (set-face-attribute 'default 
nil :height 110 :weight 'semi-light :family "Cascadia Mono") followed by 
(set-face-attribute 'default nil :height 110 :weight 'semi-light :font 
"Cascadia Mono") -- is a no-op.

You mean

            Family: Cascadia Mono
           Foundry: SAJA
             Width: normal
            Height: 105
            Weight: regular

right?  That is, the :weight 'semi-light attribute is not obeyed?  I 
observe the same behavior with Emacs 26-27-28, so at least it's not a 
regression.

Indeed.  A better way to do what you want is to move the :font attribute 
to the front:

(set-face-attribute 'default nil :font "Inconsolata LGC" :height 105 :weight 'regular)

(set-face-attribute 'default nil :font "Cascadia Mono" :height 105 :weight 'semi-light)

Likewise: move the :font attribute to the front and it will work.

The text is OK, but please put this in the manual, not in the doc
string.  If we want something to this effect in the doc string, let's
just have the first sentence there, and then a reference to the
manual.

Thanks.

Unfortunately, you also decided to take this opportunity to make
changes to which I explicitly objected in bug#57499.  I reverted that
part.  Please don't increase my load of work by making changes we
didn't agree to make.

There must be some misunderstanding here.  What I did was nothing more 
than to align the manual with the docstring, something which was forgotten 
in bug#57499.  The paragraph you now restored in the manual is similar to 
the paragraph you removed from the docstring in 89695bce3e, and the 
paragraph you added in 89695bce3e ("When a new frame is created, attribute 
values...") means, as far as I understand, the same as the sentence

If @var{frame} is @code{t}, this function sets the default attributes for 
newly created frames; they will effectively override the attribute values 
specified by @code{defface}.

which is already in the manual.

Yes.  That was the compromise we reached back then, and I want it to
stay that way.

Sorry, I don't understand what you mean.  Do you mean that the compromise 
was to remove the paragraph your removed in 89695bce3e from the docstring, 
but not from the manual?

Okay, that's not what I understood (and TBH that's still not what I 
understand now), but I don't think it's useful to continue this 
discussion.  Sorry for the additional work.

Are we sure that having order-dependent behavior is a good idea?

Since all args are available at the time of evaluation, wouldn't it be 
better to handle :font and/or :family before all the others?

I did not design that function, that's how it works.  But given how 
intricate the face machinery is, I'm not sure it's possible to do much 
better.

You may have seen in the attached patch that :family is indeed handled 
before all other attributes, but not :font.

Can you please confirm that the recipes you sent are working as expected 
when you place the :font attribute before all other attributes?

It does feel a little odd, though. Could you explain why :family does 
get evaluated first, but :font does not? And yet, it's better 
recommended to use :font?

I'm not saying these are regressions to be fixed now (Emacs 29 is too 
near), but maybe a better design is possible and not too difficult to 
transition to later.

They seem to, thank you.

Except for the frame-height-shrinking one, but that's a separate story.

I can't explain that, no.  If you look at bug#1127, you'll see that moving 
the evaluation of :family and :foundry before other attributes was (in 
2008) perceived as a workaround.  Apparently that worked well enough, and 
it's still there in its original form.

IMO it would make sense to move the evaluation of the :font attribute 
before other attributes, for the same reason.

Eli, what do you think of the attached patch?

Again, that's why I'd recommend, but it's not the officially recommended 
way of doing things (if such a thing exists).

If you want to experiment with this on master, I'm okay with trying
that there.  But not on the release branch, where I think we currently
have a reasonably good state (famous last words...) and the issue
being discussed here seems quite marginal and obscure to me to risk
destabilizing what we have.

It's not there if I use :family, though. So if from now on we recommend 
people use :font where whey might have used :family in the past, this 
might be perceived as a regression.

Indeed, that's because the :family attribute is evaluated first, and the 
:font attribute isn't.

That's what I would recommend, indeed, but I'm not the one who decides. 
The regression would be fixed by adding :font to the attributes that are 
evaluated before all others.

Yes, because it caused trouble.  See

I'd actually expect Gregory's changes to fix this, and explicitly
asked him at the time to test this bug's use case; he said back then
it was fixed.  Maybe there's some misunderstanding or fine nuances?

Are we sure the bisected change (dae3c4e89b27) itself doesn't need a 
tweak? From all the explanations here, I would expect

   (set-face-attribute 'default nil :height 110 :weight 'medium :family 
"Inconsolata")

to work correctly even without your "kludge". But it does not.

Like, okay, Inconsolata_dz has a weird "style" ("dz"), but the plain 
Inconsolata is "Medium".

Since I'm measuring window height in characters (rows) here and not in 
pixels, I don't think even the first change should happen.

Though of course the window size in pixels should change.

Plain Inconsolata is indeed medium, but Emacs now requests regular,
not medium, as the default weight.  And, according to the Fc log you
posted, Inconsolata doesn't have a regular weight variety (whose value
should be 80, not 100).

Let's wait for Martin to chime in, he's the expert on this stuff.

But when I specify :weight 'medium, shouldn't it request medium then?

You didn't just specify medium, you specified both the family and the
weight.  The implementation does it one attribute at a time (because
doing it together triggered other bugs), so at first Emacs attempts to
find a font with that family and the default weight.  And without the
kludge in font.c, that font is rejected because it doesn't have
regular weight.

Feels counter-intuitive, but all right.

I've tested the latest master, and that problem is fixed. Thanks!

The comments in the code point to bug#1127.  Maybe that problem no
longer exists, and we could avoid doing that?

Thanks for testing.

When a frame is maximized, no implied resizing is done.  With

(push 'font frame-inhibit-implied-resize)

a non-maximized frame should also keep its size in your case.

This might be a rounding error or some misunderstanding wrt what the WM
(mutter in your case?) thinks our frame size is and what Emacs thinks.
In x_new_font (in xterm.c) we do

   FRAME_COLUMN_WIDTH (f) = font->average_width;
   ...
   FRAME_LINE_HEIGHT (f) = font_ascent + font_descent;
   ...
       adjust_frame_size
       (f, FRAME_COLS (f) * FRAME_COLUMN_WIDTH (f),
        FRAME_LINES (f) * FRAME_LINE_HEIGHT (f), 3, false, Qfont);

which should have the effect that (frame-height) and (frame-width)
remain unaltered when changing the default font.  Apparently, this fails
in your case.

 > (stopping at height 5, when even the minibuffer becomes

This is a separate issue I fixed here some time ago.  But I don't
remember whether I pushed it and/or whether it requires additional
customizations to make it DTRT (it might depend on the ability to drop
window decorations one by one when a frame is shrunk).

Here as above, stepping with GDB through the x_new_font code sketched
above might help tracking down this issue.

Hi Martin,

Sorry I only got around to doing this now.

This seems to still be a problem in emacs-29, however.

Not sure if it's Mutter these days, but it's definitely GNOME Shell. 
GNOME 43.1 now (I filed this issue with a much older GNOME).

I've tried stepping through the function, and the height does shrink 
when I evaluate the previously mentioned form. Not sure which of the 
values are useful to you, which ones I should have printed along the 
way. But see the debug log at the bottom.

All this with 'emacs -Q'. It might be because of a rounding error, but 
maybe not. The bug happens with most window heights, but not with all. 
E.g., it stayed stable at (frame-height) = 36. Set it to a larger value 
- and it goes on shrinking until 36. Set it to a lower value (35 or 
less), and it does on to shrink until 10 in small steps.

Here's the debugging log. This is just one iteration.

Do I understand correctly that you see a 108 pixel decrement

 > (gdb) p f->text_height
 > $7 = 1116

...

 > (gdb) p f->text_height
 > $11 = 1008

each time you evaluate

(set-face-attribute 'default nil :height 110 :weight 'medium :family "Inconsolata")

Does the problem also happen with 'frame-inhibit-implied-resize'
non-nil?

Seems so. Or a two text-line decrease each time anyway.

But to be clear, it's InconsolataLGC here. I don't have the "plain" 
Inconsolata installed at the moment.

And :weight can be specified or not. That doesn't seem to matter:

(set-face-attribute 'default nil :height 110 :family "InconsolataLGC")

It does not.

OK.  Please apply the attached diff, do a few

(set-face-attribute 'default nil :height 110 :family "InconsolataLGC")

and tell me the contents of *foo*.  I'd like to know the size hints we
send to the WM.

Thanks, here you go.

Initially its contents are:

xg_wm_set_size_hint .. line_height .. 36 .. base_height .. 43 .. 
height_inc .. 18
xg_wm_set_size_hint .. line_height .. 36 .. base_height .. 84 .. 
height_inc .. 18

but after I eval the above (one or many times, doesn't matter), it contains:

xg_wm_set_size_hint .. line_height .. 36 .. base_height .. 43 .. 
height_inc .. 18
xg_wm_set_size_hint .. line_height .. 36 .. base_height .. 84 .. 
height_inc .. 18
xg_wm_set_size_hint .. line_height .. 45 .. base_height .. 88 .. 
height_inc .. 22
xg_wm_set_size_hint .. line_height .. 37 .. base_height .. 84 .. 
height_inc .. 18

Its contents are also no different at that "special" height where the 
frame stops resizing. Just in case that's important.

Thanks.  Please with the new patch attached eval in *scratch* the first
form

(defun foo-set-face-attribute ()
   (foo-it "set-face-attribute")
   (set-face-attribute 'default nil :height 110 :family "InconsolataLGC"))

(foo-set-face-attribute)

and then eval the last form a couple of times.  This should help us to
discern whether and how 'set-face-attribute' has an effect on the size
hints.

The contents of the buffer *foo* are below.

I'm not sure if you caught one of my previous messages, however, so I'd 
like to repeat:

The problem is easily repeatable in the above scenario. But not if I 
change "InconsolataLGC" to "Inconsolata LGC". Then the resizing stops 
after the first iteration.

In either case, 'M-x describe-face RET default' shows "Family: 
Inconsolata LGC", though. So it's not like "InconsolataLGC" is entirely 
unrecognized.

Anyway, here's the log (evaled the form 3 times):

Does it matter?  Whatever you do - have the same form evaluated twice in
a row causing a frame resize must be a bug - somewhere.

We start here

 > xg_wm_set_size_hint .. line_height .. 45 .. base_height .. 88 .. height_inc .. 22

and come up with a frame line height of 45 pixels and an increment hint
of 22 which means that some scaling (by 2 apparently) is in effect here.
Honestly, I have no idea how this is supposed to work.

Here we ask for the same (due to rounding) increment ...

... but then we do not set hints any more so it seems that we do all the
shrinking ourselves - just how can we shrink and not send size hints at
the same time is yet a mystery to me.

Please run again with the new patch but also evaluate

(setq frame-size-history '(100))

Then perform some 'set-face-attribute' calls, evaluate

(frame--size-history)

and get me the contents of both buffers *foo* and *frame-size-history*.

Thanks, martin

Yep.

I just figured that it might give you ideas as to the cause and/or 
affect the priority of having this fixed.

2x scaling, yes (I have a 4K display).

Here you go, both attached.

I called set-face-attributes 8 times, might have got a little 
over-enthusiastic.

Thanks.  It didn't harm.  IIUC the problem is in x_new_font.  With the
attached please do a few calls again and post the contents of *foo*.

FWIW I can't see anything wrong with the font.  From the earlier

xg_frame_set_char_size, visible, PS=1408x1188, XS=1408x1184
ConfigureNotify, PS=1408x1188, XS=1408x1152
xg_frame_resized, changed, PS=1408x1188, XS=1408x1152

I can only tell that, for example, we want to resize the frame from
1408x1188 to 1408x1184 pixels but the ensuing ConfigureNotify tells us
that mutter has sized us down to 1408x1152 pixels (that's the -36
increment you see every time) and we comply.  I have no idea why that
should happen - after all 1184 is (* 37 32) so it's rather the earlier
1188 that's wrong here.  But we've also set the base height to 84 and a
height increment of 18 which are both suspicious.

Anyway: I attach a new patch to shed more light on this.  Three
'set-face-attribute' iterations suffice, post me the contents of *foo*
please.

Thanks, martin

 > Aaand, here you go:

So far I'm pretty sure that we have some rounding problem here - maybe
due to scaling.  The last version of my patch is attached, please use
that for further experiments.

Now first do what you have done so far (three iterations) and post the
results.

Next, if possible, try to turn scaling off, do the same experiments and
post the results.

Finally, with scaling turned on again, start Emacs with

--eval "(setq frame-resize-pixelwise t)"

do the same experiments and post the results.

Thanks, martin

Here you go, three attachments.

As you previously guessed, the effect didn't show up when the scaling 
was off, or when resize-pixelwise was enabled.

bug#52493: 29.0.50; Setting Inconsolata up in init.el makes default face rendered wrong

 > Here you go, three attachments.

Thank you, they now contain all we need.

 > As you previously guessed, the effect didn't show up when the scaling was off, or when resize-pixelwise was enabled.

In both cases we don't scale.  Scaling introduces a rounding effect
mutter apparently doesn't like.  Take, for example, these lines of
foo-with-scaling.txt produced when we set a new font (actually the first
line belongs to the previous request and is here only to show that we
start with a frame of 35 lines):

adjust_frame_size .. old pixels/lines .. 1296 .. 36 .. new pixels/lines .. 1584 .. 35
x_new_font .. line_height .. 37 .. lines .. 35 .. new_text_height .. 1295
xg_wm_set_size_hint .. line_height & scale .. 37 .. 2 .. base_height .. 84 .. height_inc .. 18
   menubar_height .. 50 .. toolbar_height .. 82
xg_frame_set_char_size .. old .. 1584 .. arg .. 1295 .. new .. -1
   outer .. 713 .. gheight .. 858
xg_frame_resized .. old .. 1584 .. req .. -1 .. con/text .. 1260 .. 1260
adjust_frame_size .. old pixels/lines .. 1584 .. 35 .. new pixels/lines .. 1260 .. 34

The base_height value (84 pixels) we calculate here is the sum of the
line_height value, the menubar_height value and the toolbar_height
values divided by the scale factor:

(/ (+ 37 50 82) 2)

height_inc (18) is the line height divided by the scale factor (/ 37 2).

These size hints have mutter expect us to resize our frame to something
like

(+ base_height (* height_inc N))

for some positive integer N.  Now we want to resize the frame to
line_height times lines, that is (* 37 35) yielding 1295 pixels.

But (% (/ 1295 2) 18) is not zero and so mutter declines our request
giving us 1260 pixels text height instead.  Apparently, mutter starts
with (/ 1295 2) that is 647, 630 is the next multiple of 18 it finds, so
(* 630 2) is the value it concedes us.

So the height we should ask for with scaling is 1296 instead of 1295.

Please try the attached patch - I can't test it here because I don't
scale.  If it doesn't work, please post the contents of *foo* as usual.

Thanks, martin

It certainly does work. One of the changes I saw right away is the width 
of the frame right after startup with my config increased from 84 to 90 
columns. Not sure if it's good or bad, so let's go back to the behavior 
with '-Q'.

The height stopped shrinking.

The width started growing. :-D

What are you asking for in your configuration?

Repeatedly?

Not for the width.  But that's another issue.  If mutter complains about
the width not conforming to the (+ base_width (* width_inc N)) rule,
then we have already lost when the sum of fringes and scroll bar is not
a multiple of the frame's column width.  Which means, you get a "wrong"
size without any scaling and you may be lucky if that scaling does not
propagate during further 'set-face-attribute' calls.  Does each setting
of 'set-face-attribute' increase the width or is it just the first one?

Strictly spoken, Emacs is wrong here and mutter is right.  But fixing
this is quite involved since we'd have to disentangle those insane
FRAME_TEXT_COLS_TO_PIXEL_WIDTH and FRAME_TEXT_LINES_TO_PIXEL_HEIGHT
macros into xg_frame_set_char_size which would constitute a real pain.
More precisely, we'd have to treat scroll bars, fringes and internal
border like menu and toolbar and count them into the base_width value.

Try the attached which should work for any scaling and tell me what
happens now - in particular what the initial frame size is and whether
the frame grows or shrinks repeatedly.

With your latest patch it's slightly different (the max width is 84).

But what I'm also seeing, is that even without your patch the starting 
frame width is not deterministic either: the frame resizes a few times 
during loading, and may end up at width either 80 or 84. I think I 
mentioned similar behavior in some other bug report too.

So it seems like your latest patch doesn't change this behavior in any 
significant way. Still either 80 or 84, at random.

Every one (at certain starting widths), just like it was with the 
shrinking of height.

I'm sure you are right, but before we continue the thorough 
investigation, do you have any idea why

  (set-face-attribute 'default nil :height 110 :family "InconsolataLGC")

exhibits this kooky behavior, while

  (set-face-attribute 'default nil :height 110 :family "Inconsolata LGC")

does not? That might point to a weird kludge or workaround somewhere 
which just needs moving somewhere else.

Now the width shrinks. Not from all starting widths, but from many of them.

Suppose the starting width is 80 (that's what frame-text-cols returns). 
Evaluating the set-face-attribute form changes the frame size once, but 
not the width in columns. Successive invocations don't change the frame 
size.

I increase the frame to width 112 with a mouse. Doesn't shrink. 111-108 
- nope.

I resize it to 107 (according to frame-text-cols; the wm reports 
109x36), and evaluating the form shrinks the frame by 2 columns. That 
repeats until frame-text-cols is 96.

Widths 96-92 don't shrink.

I resize to 91 - it continues shrinking (in steps of 2) until 80. 80-76 
don't shrink.

75 - shrinks until 64. And so on.

What is the "max width"?  The interesting return values are those of
(frame-text-width), (frame-text-cols) and (frame-char-width) so we can
relate the previous ones.

I'm quite sure that this is due to the scroll bar width and the fringes.
You could try to make these a multiple of (frame-char-width).  That is

(+ (frame-parameter nil 'scroll-bar-width)
    (frame-parameter nil 'left-fringe)
    (frame-parameter nil 'right-fringe))

would have to equal (* N (frame-char-width)) for some N >= 0.

No idea.  You could try to step through normal_char_ascent_descent (best
when called from get_font_ascent_descent) for each of these fonts and
find out whether and how they differ.

So we at least have the improvement that the frame does not change size
for repeated, apparently idempotent, invocations.  Right?

Does shrinking the height with the mouse work as expected?  I'm quite
confident that neither of these can work reliably - after all, the one
pixel lost during rounding will continue to affect the intuitive
behavior.  I'd say that it's already a success when attempting to shrink
the frame with the mouse does not increase it initially.

Our handling of size hints is antediluvian.  In particular when
'frame-resize-pixelwise' is nil and on the other end a presumably
Teutonic WM designer interprets size hints literally.  I can try to come
up with a patch for these but don't expect too much.

Max among the return values of (frame-text-cols). With the next-to-last 
patch it was 90.

When frame-text-cols is 84, it's (+ 32 8 8) = 48, frame-char-width=17

When frame-text-cols is 80, all the above values are the same.

Oh, BTW, I have menu-bar, scroll-bar and tool-bar all disabled. The 
fringes should be on, though.

I'm reasonably certain it's the same font.

Evaluating either form ends up with the same face definition, IIUC. At 
least the output of 'M-x describe-face RET default' is exactly the same 
after either (I checked with 'diff'):

            Family: Inconsolata LGC
           Foundry: PfEd
             Width: normal
            Height: 109
            Weight: regular
             Slant: normal
        Foreground: black
DistantForeground: unspecified
        Background: white
         Underline: nil
          Overline: nil
    Strike-through: nil
               Box: nil
           Inverse: nil
           Stipple: nil
              Font: #<font-object -PfEd-Inconsolata 
LGC-regular-normal-normal-*-29-*-*-*-m-0-iso10646-1>

LGC-regular-normal-normal-*-29-*-*-*-m-0-fontset-auto2
            Extend: nil
           Inherit: nil

If you think it will help, I can still try stepping through the 
functions you mentioned, but no earlier than tomorrow.

For some frame widths it does not. For others (for ranges of widths) -- 
it does.

Resizing with the mouse works without any apparent glitches. The corner 
of the frame follows the mouse almost exactly, within the margin of a 
char's height/width (when resizing is not pixelwise).

Then try setting the fringes to one 'frame-char-width' each or set them
to zero.

Please do that.  'describe-face' is one thing.  What the display engine
thinks of a font might be another.

I see.

It should do that in terms of whatever we ask for in the width and
height increments - after all, those mouse operations are under full
control of the WM.  Whatever size the WM gives us, we comply.  Take
these two assignments in xg_wm_set_size_hint:

   size_hints.width_inc /= scale;
   size_hints.height_inc /= scale;

Instead of the "/= scale"s put some assignments with arbitrary constants
there, say

   size_hints.width_inc = 51;
   size_hints.height_inc = 7;

You should see that mouse dragging will resize the frame by exactly what
you've put there.  BTW: Try with these two lines commented out and tell
me whether mouse dragging becomes _perceptibly_ worse.  Removing them
could be a substantial relieve in the future.

The problems start after Emacs takes the values it has been told by the
WM and tries to retrofit them into its own lines/columns framework.
When you next ask Emacs programmatically to resize the frame in terms of
the values it stored there, all those rounding and scaling errors that
piled up fire back.  Resizing frames is a continuous dialogue between
Emacs and the WM.  If one of them refuses to listen to the other, users
will suffer.

where each x_new_font paragraph corresponds to one evaluation above.
Note the following two properties:

- As soon as things clear up, the size of the frame in text characters
   is 80x36 and never changes after that.  The same will have to hold for
   your 'set-face-attribute' calls regardless of what the pixel sizes
   say.

- "outer rest 0x0" stands for a zero rest when dividing the requested
   size minus the base size by the size increments.  The same will have
   to hold for your 'set-face-attribute' calls.

Maybe I'm just lucky here or it's because I do not scale.  I invite
everyone on GTK with some spare time to apply the attached
x_scale_font.diff, do some random 'set-face-attribute' calls and consult
the contents of the *foo* buffer.  If the two properties don't hold,
something might be wrong and we should investigate that.

Two points:

- My personal init script still results in a frame that's 84 columns 
wide (according to frame-text-cols). There are no frame size settings in 
the configuration.

- There are still widths of the frame where evaluating the previously 
mentioned set-face-attribute form results in the frame shrinking 
repeatedly until it reaches one of the "stable" widths. Like in prevous 
test, the width 80 is stable. IOW, nothing seems to have changed WRT to 
the shrinking behavior.

Here are the contents of *foo* accompanying the 'emacs -Q' session where 
I first resize the frame to 90 columns (according to the wm) using the 
mouse, and then evaluate the set-face-attribute form 7 times until it 
reaches the width 80.

It does have a number of lines where "outer rest" is followed by values 
other than 0x0. It's only 0x0 at the end.

Apparently, rounding the native pixels doesn't make sense.  Let's round
just the outer pixels instead.  Patch attached.

I'm not seeing much of a change, if any:

- My init script stills results in a frame 84 columns wide.

- The frame still shrinks at certain width ranges.

Attached are the contents of foo after doing this:

   (set-frame-width nil 102)
   (set-face-attribute 'default nil :height 110 :family "InconsolataLGC")

The second line was evaluated 5 times.

Thanks.  It seems that we really have to disentangle the entire size
hint stuff to get reasonable outer sizes.  Next patch attached.

- frame-text-cols from my init script is still ends up at 84 cols.

- 'emacs -Q' has its height shrinking again now.

- Its width is shrinking too, at certain widths. Not at 80 cols.

So I double-checked -- and both behaviors with the latest patch match 
what the current (unpatched) emacs-29 does. I just hadn't noticed width 
shrinking because I haven't tried to resize the frame first.

Attached are the contents of *foo* again after

(set-frame-width nil 102) ; x1
(set-face-attribute 'default nil :height 110 :family
"InconsolataLGC") ; x6

bug#52493: 29.0.50; Setting Inconsolata up in init.el makes default face rendered wrong

 > So I double-checked -- and both behaviors with the latest patch match

With one subtle difference: In the unpatched version the WM shrinks the
size.  In the patched version we do it ourselves and the WM does what we
are asking for.

   x_new_font old char size 18x36 new char size 21x45 text chars 102x36 old text pixels 1836x1296 new text pixels 2142x1620
   xg_wm_set_size_hint scale 2 char width 21 toolbar 0 vscroll 32 fringes 16 borders 0 base width 34 width inc 10
       char height 45 menubar 50 toolbar 82 hscroll 0 borders 0 base height 88 height inc 22
   xg_frame_set_char_size old native pixels 1884x1296 new native pixels 2190x1620 outer pixels 1094x858 outer rest 0x0
   xg_frame_resized old native pixels 1884x1296 new native pixels 2188x1584
   adjust_frame_size old native pixels 1884x1296 new native pixels 2188x1584 old text pixels 1836x1296 new text pixels 2140x1584 old text chars 102x36 new text chars 101x35

Here we round down the outer pixel sizes from 1095x876 to 1094x858 to
meet the WM requirements (outer rest is 0x0 in all your steps).  So
incidentally, I reverse-engineered the WM.  Now let's try to round up
instead.  I'm quite confident that this will make your frames grow.

Nope.

But this one seems the best one yet:

- No height shrinking.
- Width shrinks only once (at certain rare widths), and after that it is 
stable.

bug#52493: 29.0.50; Setting Inconsolata up in init.el makes default face rendered wrong

[Gregory Heytings]

Another user reported an apparently similar problem in bug#60585.  It 
disappears when scroll-bars are turned off.  Is that by any chance also 
the case for the problem you see, Dmitry?  It's not a proper solution of 
course, but it might perhaps hint at a proper solution.

I checked with and without the last patch (the base behavior of 
emacs-29): the scroll-bar doesn't seem to make a difference.

The original complaint was about height shrinking anyway, and the only 
scroll-bar visible by default is the vertical one (on the right). It 
doesn't seem likely that it would affect the calculation of the window's 
height.

Hmmm...  Then can you perhaps also try with and without the menu-bar and 
the tool-bar?  Unless both are already disabled in your configuration, of 
course.

IIRC think we've tried this already in this thread.

Anyway, tested this again: no change.

Okay, so it's something similar but different from bug#60585.

 > Another user reported an apparently similar problem in bug#60585.

Looking at that thread I noticed the following:

1. Why does

   I have just pulled latest Emacs and used with -Q option:
   `global-text-scale-adjust' which I have used last days upon first
   startup.

try to adjust the frame size in the first place?  IIUC it should do that
iff 'global-text-scale-adjust-resizes-frames' is non-nil and that option
is nil with emacs -Q.

2. This argument brought by gijsbers on
    https://github.com/ice-wm/icewm/issues/115

   If you look at the height of 761 then 761 - 71 is not a multiple of the vertical increment 22.
   Hence the height is adjusted to 753, because (753 - 71) / 22 = 31 exactly.
   Maybe the size is adjusted to match the Inc and Base.

is valid.  We'd have to investigate how we produce these values.

3. OTOH this argument again brought by gijsbers on
    https://github.com/ice-wm/icewm/issues/115

   IceWM historically has ignored the USSize field in the WM_NORMAL_HINTS
   property. To enforce a size an app must set both the PMinSize and the
   PMaxSize to the same value. Because there is no PMaxSize, icewm is free
   to adjust the size to a value which is in accordance to the emacs
   provided PBaseSize and PResizeInc. See the ICCCM for details. IceWM is
   still standards conformant. It just has a different interpretation than
   other WMs.

is not valid IMO.  min_width and min_height specify the minimum sizes
that should be applied, for example, when the user tries to shrink a
window with the mouse by dragging one of its borders or edges.  Emacs
does not handle these reasonably well but here I can see them with
applications like Firefox or Thunderbird.  Together with max_width and
max_height these can be used to specify a fixed-size window.  But "To
enforce a size an app must set both the PMinSize and the PMaxSize to the
same value." is something I cannot derive from any sources I have on
this subject.

This ordering in EmacsFrameResize

   change_frame_size (f, ew->core.width, ew->core.height,
		     false, true, false);

   if (get_wm_shell (widget))
     update_wm_hints (get_wm_shell (widget), ew);

makes no sense.  We first ask for a size change and then update the size
hints.

As I just said in bug#60585, the bug seems to be specific to that window 
manager (or at least to a few window managers), and disabling scroll-bars 
or setting frame-resize-pixelwise to t fixes that problem.  OTOH, what 
gijsbers says does not seem unreasonable to me (but I'm not at all an 
ICCCM expert), and I see here

https://specifications.freedesktop.org/wm-spec/wm-spec-latest.html

that "Window Managers can identify a non-resizable window because its 
minimum and maximum size in WM_NORMAL_HINTS will be the same." and that 
"Windows can indicate that they are non-resizable by setting minheight = 
maxheight and minwidth = maxwidth in the ICCCM WM_NORMAL_HINTS property."

I found another window manager which behaves similarly: Openbox.  I'm not 
100% sure the cause is the same, but the two workarounds above also fix 
that problem under Openbox, and I see this in its source code:

/*! The minimum size of the client window
   If the min is > the max, then the window is not resizable
*/
Size min_size;
/*! The maximum size of the client window
   If the min is > the max, then the window is not resizable
*/
Size max_size;

I'm quite sure that even with scroll bars disabled the problem can
happen.  'frame-resize-pixelwise' OTOH means that size increments can be
ignored by the WM so that should fix the problem indeed.

Right.  But we eventually do want to resize that frame later and as soon
as the new character sizes make it to the size hints we see the effect.

I've been following along this bug report because I was seeing something
similar. I'm using the sway Wayland wm, with this in my init:

(add-to-list 'default-frame-alist '(font . "Inconsolata-12"))

Turning scroll bars off also fixed it for me. I can't even quite
describe what "it" was, but lettering looked a little vertically
stretched and "ugly".

Here we calculate outer_width as (/ (+ 1921 32 16) 2) that is 984 and
outer_height as (/ (+ 1332 50 82) 2) that is 732.  Since 1921 is impair
we lose one pixel due to scaling.

Now width_rest calculated as (% (- 984 32) 8) and height_rest calculated
as (% (- 732 84) 18) are both zero so we do not do any compensating and
lose one column after resizing.

I attach a version to handle this particular case.  Let's see whether it
breaks something else.

Thanks, it's almost perfect:

- My init script ends up at 80x36 pretty reliably, after a bunch of 
frame resizings.

- There seems to be no scenario for successive set-face-attribute calls 
to keep resizing the frame.

Here's a few more complex ones that seem off:

;;; Scenario 1
;; 1.
(set-face-attribute 'default nil :height 110 :family "InconsolataLGC")
;; to get the frame sized right
;; call (set-frame-size nil 80 36)
;; or (set-frame-size nil 160 36)
;; or don't if the frame is at that size already (which it should be)
;; (frame-text-lines) returns 36
;; 2. !important
;; manually resize the frame using the mouse to have one line less
;; (frame-text-lines) will continue to return 36
;; 3.
(set-face-attribute 'default nil :height 110 :family "InconsolataLGC")
;; The frame will get resized to the previous dimensions.
;; Note that the return value of (frame-text-lines) doesn't change.

;;; Scenario 2
;; Do the same steps, except for the width instead of height.
;; Optionally, use different dimensions:
;; (set-frame-size nil 160 36)
;; These are the only ones I found to have this effect for both dimensions.
;; I'm guessing 160x72 will work as well, but that's bigger than my screen.

;;; Scenario 3
;; 1. From Scenario 1.
;; 2. Resize with the mouse both width and height, to have 1 less.
;; 3. Eval the set-frame-attribute form. Nothing happens, the frame size 
stays the same.
;; Step 2 still doesn't change the return values of frame-text-cols/lines.

Attaching the contents of foo for all scenarios.

These are very much non-critical, of course.

Note that a frame with the "right height" is only one where

(= (* (frame-char-height) (frame-text-lines)) (frame-text-height))

holds.  Here, for example, a maximized frame does not have the "right
height".

Manually resizing a frame with a scaling factor of 2 will be off by one
pixel when the font has impair height.  There is nothing we can do about
that - the height increment we send to the WM must be an integer.  The
result is that while the frame's pixel height changes and so does the
height of the frame on the display, the height in lines stays the same.

Hopefully so.  It's crucial that all executions of

(set-face-attribute 'default nil :height 110 :family "InconsolataLGC")

starting with the same number of text lines result in the same pixel and
text heights.

IIUC this scenario is just a variation of the first one - with a
character size of 17x37 you will lose one pixel in both dimensions.

IIUC these steps

xg_frame_resized old native pixels 1424x1368 new native pixels 1408x1368
adjust_frame_size old native pixels 1424x1368 new native pixels 1408x1368 old text pixels 1376x1368 new text pixels 1360x1368 old text chars 80x36 new text chars 80x36

represent two mouse operations that resize the frame by 16 pixels, first
the width, then the height.  Both are less that the character size so
while again the size of the frame should have changed, the numbers of
text characters didn't.

x_new_font old char size 17x37 new char size 17x37 text chars 80x36 old text pixels 1360x1332 new text pixels 1360x1332

x_new_font old char size 17x37 new char size 17x37 text chars 80x36 old text pixels 1360x1332 new text pixels 1360x1332

Here we have (= (* 80 17) 1360) and (= (* 36 37) 1332) so
adjust_frame_size triggered by x_new_font correctly decides that the
frame size should stay the same.

Yeah ok, but none of the frames were maximized in those scenarios. And 
the resizing by mouse "snapped" to the provided grid.

I'm probably out of my depth here, but with 2x scaling, shouldn't the 
height increment just be 2x larger than the original one? If N is 
integer, 2xN must be an integer as well.

Pixel dimensions do change in this scenario. But not the reported text 
height.

Yes, just width instead of height.

The frame size didn't change either, however.

All right. Where do we go from here?

The usability problems remaining are very minor, so if you're saying 
Emacs is going right thing, we might as well go with the latest patch 
and call it a day. Thank you.

I mentioned it because that's how it usually can be reproduced easily
with emacs -Q.

 > And the resizing by mouse "snapped" to the provided grid.

The resolution of that grid is specified by Emacs via these four lines

   size_hints.width_inc = frame_resize_pixelwise ? 1 : FRAME_COLUMN_WIDTH (f);
   size_hints.height_inc = frame_resize_pixelwise ? 1 : FRAME_LINE_HEIGHT (f);

   size_hints.width_inc /= scale;
   size_hints.height_inc /= scale;

If you scale by 2 and you have a font with impair sizes, you lose one
pixel and the grid will be smaller than the character size.  If we round
up in the last two lines, the grid will be larger than the character
size by one pixel.  If we do not scale, the grid will have a resolution
of two characters.  What would you prefer?

You're scaling down whatever you display probably because otherwise
displayed objects would appear to small for your eyes.  That is, while
Emacs lives in a 4000x2000 pixels world say, it's presented to your eyes
in a 2000x1000 pixels form.

Right.  That's what rounding is all about

That's not what the numbers say.  The first time, the width changed from
1424 to 1408 pixels.  The second time, the height changed from 1368 to
1332 pixels.

 > All right. Where do we go from here?

I think you should use the attached in your daily work.  It's the same
as before with the tracing code omitted.  If there are bigger problems,
use the former patch and post me the contents of *foo*.

Note that I won't install anything in the near future because I've given
up synching with the repository.  The last time I did, I spent a couple
of weeks to fix whatever got broken here.

So... the window manager works with "unscaled" pixels it has to multiply 
by 2? That's why we try to send half the actual value?

The current behavior seems more intuitive. Too bad we can't make it 
behave precisely, but oh well.

I was talking about the Scenario 3: the frame dimensions (pixelwise) 
didn't change in it.

Thank you, but I'm not sure my work is particularly affected by it. 
Having the frame width settle on 80 chars is pretty nice, I suppose, but 
after that I usually maximize the frame anyway. Or make it take half the 
screen.

I believe getting the details right is important, but it's probably not 
worth too much as a personal patch.

It would be nice, though, to avoid the frame size contortions during 
startup. I think it goes through 4 different sizes, at least. This patch 
doesn't seem to change the number of transitions, however.

Is there anything I can do to help? Your patch applies cleanly to the 
emacs-29 branch, at least.

If you send the patch together with a commit message, I can install it

 > So... the window manager works with "unscaled" pixels it has to multiply by 2? That's why we try to send half the actual value?

We send half the actual value because Robert (IIRC) has coded it that
way.  I never scale here and so I can't tell whether that's the right
approach.  Have a look at Bug#20432 where Jan says something about GTK
messing things up.

 > I was talking about the Scenario 3: the frame dimensions (pixelwise) didn't change in it.

Please tell me precisely where it didn't change.  The only cases where
it did not change are the last two lines below.  And these represent the
cases we wanted to fix.

Make it take half the screen?  This works here (xfwm4) only with
'frame-resize-pixelwise' enabled.

Conceptually, most of these contortions should happen with a yet
invisible frame.  Also, font-related contortions are a pain because
(IIUC) it takes some time to get the size of the default font as
specified by the user's init file.  If Emacs were to start with a fixed
initial pixel size, things were easier.  After all, Emacs is the only
application I know that specifies the size of the initial window WRT
some user specified font.

But don't worry: When you are using a separate minibuffer frame, Emacs
will start with one frame, create two additional ones and delete the
first one afterwards.  That's what I call real contortions.

I'll try to come up with a few comments in the code so you can install
it on master.  We might be able to simplify it later using the idea I
had for Bug#60585.  But there so far I was not able to convince anyone
of trying the patch I sent - and that one is much more involved.

Itʼs done that way because thatʼs the way it works, not because of any
decision on my part. When scaling is in use, a screen that has eg
1920x1080 "physical pixels" is presented to us as being 960x540
"virtual pixels". Since Emacs uses physical pixels internally, we need
to divide all the numbers by 2.

That's what I understood from your code and also tried to tell Dmitry.
So I suppose that GTK and the WM deal with virtual pixels only and the
gtk_window_resize API is what separates us from them.  But I've never
been able to understand where we translate virtual size values back to
our ones whenever we call xg_frame_resized.  Bear with me - I have no
good idea how scaling works internally.

But depending on the scaling of the display, the :height attribute of a 
face translates to a different height value in pixels, doesn't it?

So at some point there has to be some scaling up performed first. I 
suppose the uneven height of a font in pixels might be picked up because 
that's the closest available shape, but perhaps the "actual" doubled 
height value might be used for line height etc?

I'm just guessing, sorry if that's way off.

He also says something about "doing things correctly in the trunk now".

The scenario number 3 (where both dimensions are off by 1).

The last two lines are indeed the ones that were printed when I 
evaluated the set-face-attribute call.

I now re-read your previous message, and it made sense. No need to 
continue with this particular inquiry, thank you.

Seems to work fine here (in GNOME) either way. But it's possible that my 
screen width is just a convenient multiple of a char width, or very 
close. Anyway, I don't stay with side-by-side configuration for a long 
time either, it's mostly for bug reporting and associated testing.

In an ideal world, I would expect this to result in just 2 frame 
configurations: before and after the default face was changed. Oh well.

Sounds fun.

I have tried it, but it seems to make no difference over here.

I cannot reproduce the problem reported in bug#60585, with or without 
that patch (with GNOME).

It doesn't seem to change anything WRT behavior discussed in this one.

That one is a real treat, however.  With our current bug we are occupied
with things going awry when we want to explicitly change the size of a
frame.  In Bug#60585 we do not want to change the size of a frame.
Rather we want to keep its size fixed when changing the default font's
size.

The problem is not reproducible with GTK because there we set the size
hints only when we want to resize a frame.  With the Lucid build we set
size hints more often.

Indeed.

OK, I have recompiled to Lucid, reproduced the problem and indeed your 
patch seems to fix it. With seemingly no adverse effects.

I did get a segfault once when testing this, but wasn't able to 
replicate it so far. Could be unrelated. Attaching both it and the 
"decoded" version, which was produced with this command (note that the 
regexp is different from what the manual advises):

sed -n 's/[a-z0-9_/-]\+(\([a-z0-9+]\+\))/\1/p' segfault.txt | addr2line 
-C -f -i -p -e src/emacs

Not sure if you need the contents of *foo* from me, but attaching it 
anyway (from a different session), because it might show something 
different with 2x scaled display.

Thanks.  This shows that we have to deal with an increasing number of
window managers that pay more attention to size hints than we have
bargained for.  If Emacs doesn't keep pace with that development,
leaving 'frame-resize-pixelwise' at nil will become an obsolete option
soon.

Did this happen with emacs -Q?  An optimized build probably?  Also the
line numbers do not really correspond to neither emacs-29 nor master as
I can check from here via savannah.  In either case, dumping traces to a
buffer can produce all sorts of problems, although I try hard to do that
in "safe" places only.  So it might be related.

Now I'm confused.  How on earth do we scale with Lucid?  If we do, then
please show me how Lucid handles the Inconsolata scenario.  And please
try also the Inconsolata scenario with a GTK build and the new code.  I
doubt that the code can handle it out of the box but maybe we can tweak
it sufficiently.

Thanks, martin

'emacs -Q', a build from master with your patch applied.

Apparently, we do scale with Lucid. Even the scroll bar probably 
(although that one is harder to tell).

The InconsolataLGC problem doesn't reproduce on current master with 
Lucid, without any extra patches.

x_rest.diff?

It doesn't seem to make any effect on the problem behavior.

Attaching *foo* after 2 evaluation, then resizing the frame with a 
mouse, then 2 evaluations again.

Thanks, this one reminds me of some previous patch in the respective bug

resizing the frame with the mouse and then evaling the 
set-frame-attribute form resizes the frame (in the smaller direction).

foo attached.

That's the one where we then tried to make the frame larger by an entire
size increment minus the scaling residue.  Which means that here we
should make the frame larger by an entire size increment in the hope
that we size it back when we get notified.  Please try again.

I'm not sure what to do here.  As we previously discussed, you contract
an off-by-one pixel error every time you resize the frame with the mouse
and the default font has impair size.  That pixel is lost in the frame
size the WM allots us.  So after N mouse operations we are usually off
by N pixels unless N equals the size of the font in which case the
deviation should be compensated by our calculation of the text size in
chars.

So the size adjustments you see in the latest two patches are inherently
correct - they restore the text pixel size of the frame as the product
of the character and font sizes.

We could try to make 'set-face-attribute' adjust the pixel size of a
frame iff this would also change the size in text characters.  Hiding
the rest in the base sizes would allow such behavior now.  But how would
we explain such behavior to the user?  Also such a beast is non-trivial
to implement - I have no idea what else it could break.  Try the
attached and let's hope that it won't blow up your frame.

The previous scenarios (with one of the patches from the other bug 
thread) had frame at "impair" size only after some resizings with the 
mouse. For most sizes the frame ended up at "correct" sizes, but there 
were relatively rare sizes where this was not the case.

With your last patch here, however, the frame seemingly ended up at an 
"impair" size every time I resized it with the mouse.

With this patch 'emacs -Q' starts up at 32x6 columns/lines. :-)

Very small window, that.

Otherwise, the behavior seems pretty stable:

- Repeated invocations of set-face-attribute don't change frame size,
- After resizing with the mouse, at some frame sizes set-face-attribute 
does cause one resize (e.g. at 80x30, according to GNOME), but most do 
not -- just like the older patch I referred to in the first paragraph.

For reference let's try to stick to the last x_scale_font.diff patch I
sent you.  What was the "impair" size there?  Note in all theses cases:
The real size of a frame as it is displayed (or better cut off) by the
WM is only reflected in our pixel sizes.  The character sizes (including
those displayed by GNOME) are just approximations which reflect the
displayed sizes faithfully iff when multiplied by the character sizes
they result in the corresponding pixel size.

The present one or the one I sent you before?

According to https://debbugs.gnu.org/cgi/bugreport.cgi?bug=52493#332, 
some impair sizes were 80x36 minus 1 in any dimension using the mouse.

Sure.

The one from the message in this thread which I was responding to. File 
called x_rest.diff.

Sorry, forgot about it last time. So, with x_rest.diff, the attached 
transcript is of:

1. Resizing the frame to 80x36 (according to GNOME).
2. Evaluating the set-face-attribute form twice.
3. Resizing the frame to 80x20 (per GNOME), which is 76x20 according to 
our internal measurements.
4. Evaluating the set-face-attribute form twice again.
5. Resizing to 80x32.
6. Evaluating s-f-a twice again.

In this scenario, step 4 doesn't change the frame size. But if I skip 
step 1, step 4 (evaluating s-f-a after resizing to 80x20) does change 
the frame size. And step 6 (s-f-a at size 80x32) does not.

So it seems the history of size changes now (?) affects which sizes are 
"impair".

Also, only height is important now: if height 20 is "impair", then I can 
resize the frame to any width with this height, and evaling s-f-a will 
shrink the frame in both dimensions by one char. Same for height 34 in 
the alternative scenario.

You mean the ones where you resized a frame with the mouse by 16 or 36
pixels with a character size of 17x37?

Do you mean that 80x36 according to GNOME is 80x36 according to our
internal measurements while 80x20 to GNOME is 76x20 according to our
internal measurements?

Didn't we always have that?  The present code simply tries to reduce
some noise when setting the font would otherwise cause a resize of a few
pixels.

Please try the next patch so at least the initial size becomes
reasonable again.

Not at all, I just got a little tired looking up our internal 
measurements every time. GNOME's measurements, OTOH, are listed under 
the mouse while I'm resizing the window.

I wasn't sure you really needed the internal ones here, so at some steps 
I only mentioned GNOME's ones.

Not to my recollection. If the current pixel dimensions of the frame are 
FONT_HEIGHT*LINES-1, wouldn't that be a stable condition?

I could be wrong, though.

It does, thank you.

Here's a new scenario (very much similar to the old one):

1. Evaluate s-f-a twice.
2. Resize to 80x18 (internally it's 76x18).
3. Evaluate s-f-a twice.

The transcript attached, in case it's useful. But I guess, as per the 
previous discussion, this is the point where we could stop, with no 
further improvement feasible.

I'm afraid I don't know whether the filter worked at all.  Please try
with the next patch two or three times to

(1) resize the frame with the mouse by two or three lines or columns or
     both, and do

(2) 'set-face-attribute'

The idea is that (2) should not try to change the frame size by a very
few pixels (less than the font size) only and that in the *foo*
transcript lines starting with "xg_frame_set_char_size_return" appear
confirming that the filter was effective.

It seems to have a different effect: the last version at least has one 
size where s-f-a changes the height by 2 line heights.

See this transcript where at the end (and multiple times before that) 
change the frame to 118x35 (per GNOME) which is 112x35 internally, and 
s-f-a changes the height to 33 (per GNOME) which is 34 internally.

The lines xg_frame_set_char_size_return do appear in the transcript.

I suppose you're talking about this part:

x_new_font old char size 17x37 new char size 17x37 text chars 112x35 old text pixels 1904x1330 new text pixels 1904x1295
xg_frame_set_char_size old native pixels 1952x1330 new native pixels 1952x1295 outer pixels 976x713 outer rest 0x0
xg_frame_resized old native pixels 1952x1330 new native pixels 1952x1294
adjust_frame_size old native pixels 1952x1330 new native pixels 1952x1294 old text pixels 1904x1330 new text pixels 1904x1294 old text chars 112x35 new text chars 112x34

And what you probably mean here is that you've seen the GNOME window
show 118x35, then you did 'set-face-attribute' and after that the GNOME
window showed 118x33.  The explanation is probably that GNOME shows the
N from the

   frame_height = base_height + N * height_inc

calculation and after 'set-face-attribute' already removed one line,
increasing base_height to make the equation hold removed another one.

I attach a patch where I try to mimic in *foo*, after a text "WM hint",
what a WM would typically show there.  Please switch to *foo* right away
and, while you drag a border, check whether the numbers are the same
GNOME displays.  If so, please show me again the transcript of the
above.  (118 vs 112 looks slightly preposterous BTW - it would mean that
scroll bar and fringes are six characters wide.  Here both width and
height differ by 1 only.)

I underestimated the scaling effect.  With a character width scaled from
17 to 8 a base_width of 32 and a native width of 1952 pixels we get

(/ (- (/ 1952 2) 32) 8) ~> 118

On the other hand with 1904 text pixels (scroll bar + fringes are the
remaining 48 pixels) and the unscaled character width we get

(/ 1904 17) ~> 112

This shows how scaling strongly affects whatever GNOME displays here and
what Emacs uses internally.  It might be illustrative to put two equally
sized frames above each other - one from a GTK and one from a Lucid
build - and look at what size hints GNOME displays for each of them.

For the rest, the transcript nowhere shows that the GNOME hints jump by
two or more after 'set-face-attribute'.  Can you spot such behavior?

There are jumps like these

xg_frame_resized old native pixels 1472x1368 new native pixels 1568x1404
adjust_frame_size old native pixels 1472x1368 new native pixels 1568x1404 old text pixels 1424x1368 new text pixels 1520x1404 old text chars 83x36 new text chars 89x37

     base_size 32x84 size increments 8x18 WM hint 120x42

during mouse dragging.  But these result from redisplay lagging behind
your drag speed.  Hence subsequent drags are collapsed into larger ones
and Emacs "adjusts" the frame size only after redisplay has decided in
good faith that it now can present the frame to your eyes.

Let me know if you really need that -- I'd have to compile Emacs in two 
separate directories.

The jumps in the log look smooth, but one set-face-attribute evaluation 
creates several log entries. After I resize the frame to 118x35 and 
evaluate the s-f-a form, all of this is printed in the log:

...and the frame is 118x33 at the end, naturally.

Then I can resize the frame again, this is printed:

Then I call s-a-f again, and a lot of stuff (slightly different: it 
seems the xg_wm_set_size_hint calls is missing) is printed again:

One of these days please do.  Eventually we need someone to tell us how
Lucid builds scale and whether the results look different from the GTK
builds.  If nobody knows, we could try to guess from what Lucid and GTK
frames look like on your display.

This means that if you are sure that you have called it once only,
'set-face-attribute' manages to run set_new_font_hook twice.  Which
would be a real pain.  Maybe someone has an idea.  Otherwise I have to
invent a counter, increment it in 'set-face-attribute', print it in
x_new_font, have you test it again ...

OK, I have done so now.

First of all, they start up with different dimensions: Lucid's is a bit 
shorter and narrower. GNOME says Lucid is 78x34 and GTK3 is 79x35.

Internally, both think they are 80x36.

The end of *foo* for GTK3 contains:

xg_frame_resized old native pixels 1488x1296 new native pixels 1488x1346
xg_frame_resized old native pixels 1488x1296 new native pixels 1488x1296
xg_wm_set_size_hint scale 2 char width 18 toolbar 0 vscroll 32 fringes

     char height 36 menubar 50 toolbar 0 hscroll 0 borders 0 text height 
648 base height 43 height inc 18
xg_wm_set_size_hint scale 2 char width 18 toolbar 0 vscroll 32 fringes 
16 borders 0 text width 720 base width 33 width inc 9
     char height 36 menubar 50 toolbar 82 hscroll 0 borders 0 text

xg_frame_set_char_size old native pixels 1488x1296 new native pixels 
1488x1296 outer pixels 744x714 outer rest 0x0
     base_size 33x84 size increments 9x18 WM hint 79x35

And for Lucid, it contains:

EmacsFrameResize old native pixels 1474x1332 new native pixels 1474x1354
EmacsFrameResize old native pixels 1474x1332 new native pixels 1474x1354

1474x1354 old text pixels 1440x1296 new text pixels 1440x1296 old text 
chars 80x36 new text chars 80x36

(I avoid inserting the full contents for brevity, they are several times 
longer in both cases.)

Lucid's menu bar and tool bar look shorter in height, with less padding. 
The font size seems to be equal, however. And the tool bar icons are 
scaled on Lucid too.

I tried to resize them, but (as long as pixelwise resizing is disabled), 
they don't match exactly. But if I line them up very close, GNOME says 
Lucid (which is slightly larger) is 81x37 and GTK3 is 80x36. Here are 
respective logs:

GTK3:

     base_size 33x84 size increments 9x18 WM hint 80x36

Lucid:

chars 82x37 new text chars 82x38

Which is to say Lucid's log is slightly inaccurate here because, again, 
GNOME reports that window to be 81x37.

I'm pretty sure, yes. I performed that experiment and observed the log 
several times.

Would a counter really help? I guess you'll be able to confirm what I'm 
saying, but then what? Would that bring any new information?

Should we try to circle back to finding the difference between 
"InconsolataLGC" and "Inconsolata LGC"? The latter doesn't exhibit most 
of the problematic behaviors we have been discussing here.

And when s-f-a is evaluated at dimensions 118x35 with the latter family 
name, it first corrects the dimensions slightly to 118x34 (with like a 
few pixel difference in height, 2 or 3), and then no subsequent 
evaluations of s-f-a change frame dimensions, no matter how I resize it 
with a mouse first.

Visually, the resulting text seems identical between these two fonts. 
Maybe the former font name is somehow "autocorrected" into the latter? 
And that triggers some kind of callback internally that can additionally 
resize the frame?

Great.  If possible please keep the Lucid build around for a couple of
days - there are yet a lot of mysteries to solve.

Can you try both with unpatched builds?  My unpatched Emacsen start here
(according to xfce/xfwm4, no scaling) as 80x36 the patched ones as 79x35.

Same here.

Can you show me the text pixels values?  These are the ones we should
compare.  The native values differ because for Lucid the height includes
the toolbar which we draw ourselves into the rectangle the WM allots to
us.  GTK draws the toolbar into its own area which is outside the native
rectangle.

Here I would have liked to see the value for the scroll bar - vscroll.
I suppose these differ on Lucid and GTK.

When you put the two frames side by side, does the text area start lower
with GTK?  Here they start at exactly the same pixel position.  I attach
a screenshot so you can see.

 > And the tool bar icons are scaled on Lucid too.

Is that the reason for the height difference?

Lucid builds do not report the "WM hint" values (yet).  What stupefies
me most here is one thing: The Lucid build apparently also resizes in
18x36 increments although your font should ask for 17x37 pixels and we
nowhere do any scaling.  Please show me what the Lucid build outputs
after x_new_font.

Maybe.  You could try putting a breakpoint at x_new_font and, whenever
it has triggered a second time in a row after you've done
'set-face-attribute', show me the backtrace for that second time.  Then
we could find out what strange force is triggering that.  If you manage
to do that, we don't need the counter.

The first thing to try would be obvious: Does the latter trigger the
"two x_new_font entries in *foo* in a row behavior"?

Please send me the *foo* transcript for that.

Maybe fontset_from_font does such a thing.  We'd have to find out first
whether the values x_new_font finds for font->average_width and
font_ascent + font_descent differ for the two Inconsolatas.

Hi Martin,

Sorry for the pause.

Sure, it's a separate worktree, it can stay around a while.

Unpatched Lucid agrees with GNOME (both say 80x36).

GTK3 is 79x36 still, again according to GNOME.

How do I get that numbers?

In case that's relevant, (buffer-text-pixel-size) evaluated in *scratch* 
with its default message returns (1296 . 72).

   window-vscroll is a built-in function in ‘C source code’.

   Return the amount by which WINDOW is scrolled vertically.

Is that the value you were looking for? If not, please tell me how to 
find it.

It does. See the attached screenshots with unpatched builds.

More likely, the reason is smaller padding in the Lucid build -- both in 
the menu and in the toolbar.

If I understood your request correctly:

Here's the output after I evaluate s-f-a for the first time:

I think the above means that x_new_font is called for the second time 
even in the Lucid build. Anyway, with GNOME and the patch:

It is hit twice, and both calls seems to have the same backtrace.

What seems to be different between the two are the font_object argument 
to x_new_font and the arguments to Finternal_set_lisp_face_attribute at 
the end of the backtrace.

It seems like they are called twice because my original example sets two 
attributes: :height and :family.

[Po Lu via Bug reports for GNU Emacs, the Swiss army knife of text editors]

Whenever you see an inconsistency between what Emacs thinks its WM hints
are, and what you think the window manager sees, try to actually read
the window manager hints property with `xprop'.

It should print several lines describing the window manager hints.

WM_NORMAL_HINTS(WM_SIZE_HINTS):
		program specified minimum size: 34 by 55
		program specified resize increment: 8 by 17 <------
		program specified base size: 34 by 55
		window gravity: NorthWest

Check there to see if the increment is really 17x37.
Xt sometimes refuses to set hints, which can be very confusing.

Thanks.

Should this perhaps be in etc/DEBUG?

I think so.  As xprop is also useful when debugging any kind of problem
involving X window properties, so I guess the other uses should be
written down as well.

Thanks!

Lucid's hints with InconsolataLGC:

WM_NORMAL_HINTS(WM_SIZE_HINTS):
		user specified size: 1714 by 1723
		program specified minimum size: 51 by 140
		program specified resize increment: 17 by 37
		program specified base size: 51 by 140
		window gravity: NorthWest

GTK's hints with InconsolataLGC:

WM_NORMAL_HINTS(WM_SIZE_HINTS):
		program specified minimum size: 64 by 324
		program specified resize increment: 16 by 36
		program specified base size: 64 by 168
		window gravity: NorthWest

GTK's hints with "Inconsolata LGC" are the same, though:

WM_NORMAL_HINTS(WM_SIZE_HINTS):
		program specified minimum size: 64 by 324
		program specified resize increment: 16 by 36
		program specified base size: 64 by 168

I guess the Lucid build is working correctly.

Apply it on top of the already patched Emacs, correct? The one I've been 
running most of the tests lately.

During startup, it prints:

XSetWMSizeHints: 2, 2
XSetWMSizeHints: 18, 36
XSetWMSizeHints: 18, 36
XSetWMSizeHints: 18, 36

After I evaluate (set-face-attribute ...), it adds:

XSetWMSizeHints: 20, 44
XSetWMSizeHints: 16, 36
XSetWMSizeHints: 16, 36

After that, whenever the same evaluation results in frame shrinking 
(after I resized it with a mouse), it also prints

XSetWMSizeHints: 16, 36

That's it.

But if I repeat the same experiment using the value of :family 
"Inconsolata LGC" (with a space), it prints exactly the same values.

Except, since no s-f-a evaluations with that :family cause frame 
shrinking, it doesn't print any additional XSetWMSizeHints logs.

Right... thanks.

I'm interested in why XSetWMSizeHints might be called with 20, 44.
Would you please put a breakpoint there and make it conditional on
those values of hints->width_inc and hints->height_inc?

Done.

Right, thank you.  If you go up to frame 23, and then:

  (gdb) p f->size_hints
  (gdb) p f->hint_flags

What is displayed?
Also, what is:

  (gdb) p xg_get_scale (f)

?

Thanks.

What is f->column_width and f->line_height?  If you go up to x_new_font,
what is font->average_width, font_ascent and font_descent?

These ascent and descent measurements are not correct for your font,
right?  What does:

  (gdb) p font_object
  (gdb) xfont

say?

The output doesn't seem very useful:

$6 = XIL(0x55555692631d)
(gdb) xfont
$7 = (struct font *) 0x555556926318

It's what in *foo* should appear after "new text pixels".

I see.  BTW, your Lucid scroll bar doesn't seem to have a ruler (or
thumb, or whatever you call it) nor the arrows at top and bottom.

So whenever we do 'set-face-attribute' to set both :height and :family,
we do the frame resizing twice, once for the family which apparently
assigns a new character size and once for the height.  This is bad: Why
ask the WM twice to set the frame size in one and the same call?  When
'frame-inhibit-implied-resize' is nil, these calls should be collapsed
into one and setting the size hint values should be always delayed.

OK.  But what _is_ the difference between the "InconsolataLGC" and
"Inconsolata LGC" calls here?  IIUC the "called for the first time"
behavior for "InconsolataLGC" is that the second x_new_font call does
not happen.  Is that right?  Please post the respective section of *foo*
for that first call so we can compare how it differs from the
"Inconsolata LGC" one.

To elaborate: The trace you show above resizes the frame twice,
apparently once for the :height and once for the :family change.  So we
should find out why the call for "InconsolataLGC" does not try to resize
the frame twice.  It should be something like not finding a suitable
font with "InconsolataLGC" or at least one that does not ask for
changing the height

BTW - do we call x_new_font for the :height first here (which would be
bad IMO)?

We had it in *foo* but I removed it because it didn't show anything
unexpected.  Putting a breakpoint after the line

   get_font_ascent_descent (font, &font_ascent, &font_descent);

in xterm.c should do (it's probably the second hit).  Then print the
values of font->average_width, font_ascent and font_descent but make
sure to do it for both - "InconsolataLGC" and "Inconsolata LGC" - so we
can compare them.

Hi Martin,

It becomes ever more difficult to remember the context. E.g. which 
operations I should do with each build before looking up this or that value.

It seems like it would be better to just attach the foo logs for both. 
See foo-gtk3.txt and foo-lucid.txt attached.

These logs are of 'emacs -Q' followed by evaluating

   (set-face-attribute 'default nil :height 110 :family "InconsolataLGC")

Indeed. Not sure if it's supposed to.

The scrollbar itself is not very functional: it shows the scroll 
progress of the buffer, but to scroll back using the mouse clicks seems 
impossible (all scrolling proceeds in one direction).

Makes sense. Though it's hard for me to tell at which step the variable 
should be appled.

(This is while keeping the frame in its default size; no resizing with 
the mouse.)

It looks like both trigger two x_new_fonts calls the first time. And 
maybe resize the frame twice, which could be hard to register with the 
human eye. But then one continues to do that (under certain conditions), 
and another stops.

That's what I was thinking: "InconsolataLGC" falls back to "Inconsolata 
LGC", but that's not registered in some internal data structure, so 
whenever a new set-face-attribute call arrives, the comparison fails, 
and the search is repeated.

> BTW - do we call x_new_font for the :height first here (which would be
> bad IMO)?

That seems difficult to answer with gdb: too many 
internal-set-lisp-face-attribute calls during Emacs's startup.

But set-face-attribute's definition (and stepping through it with edebug 
for good measure) shows that :family is processed first.

I think this was also brought up in a recent bug discussion with 
Gregory: :family and :foundary and processed before the other 
attributes. But he recommended people used :font instead, for other reasons.

InconsolataLGC:

first hit:

(gdb) p font->average_width
$1 = 21
(gdb) p font_ascent
$2 = 37
(gdb) p font_descent
$3 = 8

second hit:

(gdb) p font->average_width
$4 = 17
(gdb) p font_ascent
$5 = 31
(gdb) p font_descent
$6 = 6

Inconsolata LGC:

Exactly the same.

Same here.  In fact, I think we have investigated most of what can be
done here.  So unless someone has a better idea I'll try to come up with
a patch that comprises most of what I sent you so far and some further
fixes - size hints on xfwm have become off by one here and I don't yet
know what causes it.

So as a general guideline I plan to cook up something like:

- Make the base size hints handle any irregularities caused by increment
   hints not being integral multiples of our line/column sizes.

- Implement correct minimum size hints and make them independent from
   the base sizes.

- Do away with our attempts to override GTK which means to get rid of
   emacsgtkfixed.c/.h.

All this will take some time and testing.

FWIW, it would be nice to get the 80x36 and 84x36 below

adjust_frame_size old native pixels 1728x1620 new native pixels 1408x1332 old text pixels 1680x1620 new text pixels 1360x1332 old text chars 80x36 new text chars 80x36
     base_size 32x84 size increments 8x18 WM hint 84x36

in synch but I have no clear idea yet how to do that.  IIRC I added the last
line to that comment in gtkutil.c

   /* Use one row/col here so base_height/width does not become zero.
      Gtk+ and/or Unity on Ubuntu 12.04 can't handle it.
      Obviously this makes the row/col value displayed off by 1.  */

some time ago but am not sure whether it explains the problem in its
entirety or something else has to be done too.

Are these toolkit scroll bars?  What are your build options for Lucid?
Whatever it is, this behavior deserves a separate bug report.

All these show no differences between the two Inconsolatas.  So the
reason why one keeps your frame shrinking and the other doesn't still
remains a mystery.

You could try with two separate 'set-face-attribute' calls.  That is: Do
the below for both Inconsolata fonts

first with only :family set leaving :height alone and then with only
:height set leaving :family alone.  Then do the reverse - that is first
with only :height set leaving :family alone and then with only :family
set leaving :height alone.

> Whatever it is, this behavior deserves a separate bug report.

Actually, it seems like I just didn't understand how to use it at first: 
when I hover the mouse over the scrollbar, a two-sided arrow appears.

With that, clicking the left mouse button scrolls the buffer in one 
direction, and clicking the right mouse button (anywhere) scrolls the 
buffer in another direction. I've very little experience with 
Lucid/Motif applications, so this took some experimentation.

And it does have a thumb when the buffer is taller than the window. 
Sometimes the thumb gets bigger and sometimes smaller, though. That's a 
little odd. Perhaps it works off the number of visible characters rather 
than lines.

Okay.

InconsolataLGC:

(set-face-attribute 'default nil :family "InconsolataLGC")

(gdb) p font->average_width
$1 = 21
(gdb) p font_ascent
$2 = 37
(gdb) p font_descent
$3 = 8

(set-face-attribute 'default nil :height 110)

(gdb) p font->average_width
$7 = 17
(gdb) p font_ascent
$8 = 31
(gdb) p font_descent
$9 = 6

Now the reverse:

(set-face-attribute 'default nil :height 110)

(gdb) p font->average_width
$10 = 15
(gdb) p font_ascent
$11 = 25
(gdb) p font_descent
$12 = 5

(set-face-attribute 'default nil :family "InconsolataLGC")

(gdb) p font->average_width
$13 = 17
(gdb) p font_ascent
$14 = 31
(gdb) p font_descent
$15 = 6

(I did restart Emacs between tries, just not GDB.)

Inconsolata LGC:

All exactly the same. Omitted to save space.

Interesting.  I've never seen such behavior.

There's one thing that we haven't checked yet and I don't know how to do
that.  When you evaluate :height first you get a line height of 30 which
scaling should reduce to 15 without loss.  When you evaluate :family
first you scale twice with a loss.  I have no idea whether this has any
impact.  You can try whether either of the following

(progn
   (set-face-attribute 'default nil :family "Inconsolata LGC")
   (set-face-attribute 'default nil :height 110))

(progn
   (set-face-attribute 'default nil :height 110)
   (set-face-attribute 'default nil :family "Inconsolata LGC"))

causes a different shrinking behavior but I doubt that it will reveal
anything useful.  So I ran out of ideas ...

Alas, I'm not seeing much of a change.

"Inconsolata LGC" is "stable" with either.

"InconsolataLGC" reliably shrinks at e.g. 104x37 (GNOME size), again, 
with either.

Sorry, here's some missing info:

I don't have a font called "InconsolataLGC", or maybe not anymore. I 
have a font called "Inconsolata LGC", with a space.

Evaluating

(set-face-attribute 'default nil :height 110 :family "Inconsolata LGC")

works okay, it's only evaluating

(set-face-attribute 'default nil :height 110 :family "InconsolataLGC")

creates this effect.

The value of 'height' is also important. E.g. it doesn't happen for 105, 
for happens for 110.

Would someone explain what the problem is, and what has already been

In a nutshell, Dmitry repeatedly evaluates 'set-face-attribute' with the
same arguments and has his frame height decrease by 36 pixels each time
he does that.

Right.  What exact invocation of `set-face-attribute'?

[martin rudalics]

(set-face-attribute 'default nil :height 110 :family "InconsolataLGC")

AFAICT the problem is either with

   get_font_ascent_descent (font, &font_ascent, &font_descent);

for that font or in an ensuing size hints base height conflict.

In another news, 65fd3ca8 (the following commit that added 'medium')

No, both it and its parent have the problem. Which kind of makes sense, 
since the commit doesn't seem to change any fundamentals, just how the 
mode-line looks.

I did 'git bisect', and it points to dae3c4e89b27.
