When starting Emacs from a terminal/console window, GTK emits the
following message in the terminal/console:
Gtk-WARNING **: gtk_window_parse_geometry() called on a window
with no visible children; the window should be set up before
gtk_window_parse_geometry() is called.
The message is emitted n - 1 times, where n is the number of
frames specified in the desktop file; with no desktop file, or
with a desktop file specifying just the one frame, no such message
is emitted.
Once Emacs is up and running, creating new frames does not cause
this message to be emitted.
I tried deleting the desktop file and starting fresh, but the
problem persists.
I'm seeing this in rc2 of Emacs 25.2 built from the tarball. I
didn't see it in Emacs 25.1. I do however see it in 25.1.91.
If needed I'm happy to try to find a minimal recipe for this from
`emacs -Q' but I would need some pointers on how to create / read
desktop files from `emacs -Q'.

Thanks. It might be enough if you run Emacs under a debugger with a
breakpoint in the GTK function which emits this warning, then show us
the backtrace from that function. That should point to the code that
gets executed when it probably shouldn't.

This warning is emitted by line 11414 of
`gtk_window_parse_geometry' in gtkwindow.c in the gtk+-3.22.8
sources. The code looks like this:
gboolean
gtk_window_parse_geometry (GtkWindow *window,
const gchar *geometry)
{
gint result, x = 0, y = 0;
guint w, h;
GtkWidget *child;
GdkGravity grav;
gboolean size_set, pos_set;
GdkScreen *screen;
g_return_val_if_fail (GTK_IS_WINDOW (window), FALSE);
g_return_val_if_fail (geometry != NULL, FALSE);
child = gtk_bin_get_child (GTK_BIN (window));
if (!child || !gtk_widget_get_visible (child))
g_warning ("gtk_window_parse_geometry() called on a window with no "
"visible children; the window should be set up before "
"gtk_window_parse_geometry() is called.");
...
There is a note in the commentary preceding the function that
echos the warning message:
* Note that for gtk_window_parse_geometry() to work as
* expected, it has to be called when the window has its “final”
* size, i.e. after calling gtk_widget_show_all() on the
* contents and gtk_window_set_geometry_hints() on the window.
The only place in the Emacs sources where I see
`gtk_window_parse_geometry' being called is in `xg_set_geometry'
at line 802 of gtkutil.c where the code looks like this:
/* Silence warning about visible children. */
id = g_log_set_handler ("Gtk", G_LOG_LEVEL_WARNING | G_LOG_FLAG_FATAL
| G_LOG_FLAG_RECURSION, my_log_handler, NULL);
if (!gtk_window_parse_geometry (GTK_WINDOW (FRAME_GTK_OUTER_WIDGET (f)),
geom_str))
fprintf (stderr, "Failed to parse: '%s'\n", geom_str);
So it looks like a previous attempt to avoid the warning message
is no longer successful.
As requested, here is the backtrace when the warning is emitted:

Thanks for the footwork and all the useful information this
uncovered. I will look closer at that later, but right now I believe
I am (or was) confused...

This seems to indicate Emacs is restoring desktop into a new GUI
session. But in your original report you said:
> When starting Emacs from a terminal/console window, GTK emits the
> following message
which I interpreted to mean you were starting "emacs -nw". Did I
misinterpret what you were saying? If so, what is the significance of
the "terminal/console window" part?

Sorry for the confusion there, Eli. What I mean(t) is that I start
a new GUI Emacs by entering
src/emacs &
in a terminal/console such as XTerm or Konsole. (This is how I
normally start Emacs.)
The only relevance of the start from the terminal/console is that
I then see the warnings and errors emitted. (If I had started it
from the window manager / desktop environment then those would not
be visible to me.)

Properly I should call it a graphical terminal emulator, I guess.
Without being aware, one gets sloppy referring to things in one's
every day world!

Right, got it.
So the question now becomes: how is invoking x-create-frame-with-faces
via frameset-restore is different from the same operation invoked,
say, via "C-x 5 b"? (I understand that the latter doesn't cause GTK
to emit the warning, right?)

Right. And the answer is that with `C-x 5 2' (and `C-x 5 b'),
while `xg_set_geometry' is called, the body of it seems to be
skipped [you had better check my use of GDB, here because the
results confuse me so maybe I'm using it wrong] so
`gtk_window_parse_geometry' never gets called.
For convenience, the full code, with line numbers, of
`xg_set_geometry' is:
(gdb) list gtkutil.c:780
775 static void
776 xg_set_geometry (struct frame *f)
777 {
778 if (f->size_hint_flags & (USPosition | PPosition))
779 {
780 int left = f->left_pos;
781 int xneg = f->size_hint_flags & XNegative;
782 int top = f->top_pos;
783 int yneg = f->size_hint_flags & YNegative;
784 char geom_str[sizeof "=x--" + 4 * INT_STRLEN_BOUND (int)];
(gdb) list +20
800 | G_LOG_FLAG_RECURSION, my_log_handler, NULL);
801
802 if (!gtk_window_parse_geometry (GTK_WINDOW (FRAME_GTK_OUTER_WIDGET (f)),
803 geom_str))
804 fprintf (stderr, "Failed to parse: '%s'\n", geom_str);
805
806 g_log_remove_handler ("Gtk", id);
807 }
808 }
809
This is my interaction with GDB after `C-x 5 2':
Thread 1 "emacs" hit Breakpoint 3, xg_set_geometry (f=0x386d000) at gtkutil.c:778
778 if (f->size_hint_flags & (USPosition | PPosition))
(gdb) print f->size_hint_flags
$3 = 0
(gdb) print USPosition
No symbol "USPosition" in current context.
(gdb) print PPosition
No symbol "PPosition" in current context.
(gdb) print (USPosition | PPosition)
No symbol "USPosition" in current context.
(gdb) print (f->size_hint_flags & (USPosition | PPosition))
No symbol "USPosition" in current context.
(gdb) n
808 }
(gdb)
Is my syntax wrong when I try to get the values?
Thanks.

FWIW, the following expands on the information in my previous
message.
I have breakpoints set a) at the entry to `xg_set_geometry' so
that I can see when it is called even when the body is not
executed, b) at the call to `gtk_window_parse_geometry' (line
802), and c) at line 806 just after the call to
`gtk_window_parse_geometry' so I can see if the GTK warning
message is emitted.
(gdb) break xg_set_geometry
Breakpoint 3 at 0x5656b4: file gtkutil.c, line 778.
(gdb) break gtkutil.c:802

1. With a desktop file that specifies three frames, the first time
we enter `xg_set_geometry' after starting Emacs (presumably when
the first/main Emacs frame is created), `f->size_hint_flags' is 0,
the body of the function is not executed,
`gtk_window_parse_geometry' is not called, and no warning message
is printed by GTK:

If the value of the hint flags is zero, none of the individual hints
will match, obviously.

It sometimes happens with preprocessor macros. The trick I use in
those cases is this:
(gdb) print USPosition+0
If even this doesn't help, it most probably means Emacs wasn't
compiled with the -g3 flag.
In any case, googling finds this:
https://tronche.com/gui/x/xlib/ICC/client-to-window-manager/wm-normal-hints.html
which shows the values of the flags.

Right. 4 is PPosition flag, AFAIU.
The only place where we set the USPosition and PPosition flags in
size_hint_flags field of a frame structure is in function
x_figure_window_size (in frame.c), when the user-position parameter or
the top/left parameters are present in the parameters of the frame
being created. And that explains the difference between restoring
desktop and simply creating a new frame: frameset.el restores the
frames at their recorded positions, which is why the PPosition flag is
set. I think you should be able to reproduce the warning with the
likes of "C-x 5 b" and even just by starting Emacs, if you arrange for
frame coordinates to be specified in the frame parameters, e.g. with
the --geometry command-line option when invoking Emacs.
So we are back at square one: we need to understand why the warning
isn't get silenced by this:
/* Silence warning about visible children. */
id = g_log_set_handler ("Gtk", G_LOG_LEVEL_WARNING | G_LOG_FLAG_FATAL
| G_LOG_FLAG_RECURSION, my_log_handler, NULL);
Can you look into the source of g_warning and see why the above
doesn't avoid these warnings, and what should we do to avoid it?
Thanks.

The only way to investigate this is by examining the parameters passed
by ‘frameset--restore-frame’ to ‘make-frame-on-display’. One of these
parameters causes the problem at hand.

I did have the `-g3' flag set. However as part of the historical baggage
in my build script I also had `-ggdb'. Removing the `-ggdb' flag fixed
this particular problem. Now I can get GDB to show me the values of
preprocessor "constants". Thanks.

Hello Eli,
I was unsuccessful in this assignment (so far at least). I suspect
the answer is that GTK is using structured logging, but that is
just a wild guess at this point.
[I don't know how to do source-level debugging of code that I
didn't build myself. Both glib and Gtk+ on my system were
built/installed by the distribution's package manager and I have
only the source code from upstream, not the source code for the
exact versions on my system.]
I did ascertain that the log handler `my_log_handler' that we
install in the code snippet above is never called.
For testing purposes, I also installed a catch-all handler, with
g_log_set_default_handler(), and that doesn't get called either.
I have no direct experience at all with either glib or Gtk+, but
the documentation at [1] [I don't know for what version this is
for, or if it's even relevant], seems to say that
g_log_set_handler() has no effect if structured logging is turned
on. It seems to say that structured logging is in effect if
G_LOG_USE_STRUCTURED is defined.
There is some indication that Gtk+3.22.8 might use the new
structured logging. For example:
$ grep -rn "G_LOG_USE_STRUCTURED" /data/projects/vc/gtk+-3.22.8/
/data/projects/vc/gtk+-3.22.8/gdk/mir/Makefile.in:526: -DG_LOG_USE_STRUCTURED=1 \

I don't have any more direct evidence at this stage. I might press
on with this enquiry, but I admit I am way out of my depth at this
stage.

Hi Martin,
Is there anything in particular you'd like me to report, or do you
want to see everything passed to `make-frame-on-display' by
`frameset--restore-frame'?
Thanks,

Sorry, I omitted the reference:
[1] https://developer.gnome.org/glib/stable/glib-Message-Logging.html
It says (amongst other things):
- "To use structured logging (rather than the old-style logging),
either use the g_log_structured() and g_log_structured_array()
functions; or define G_LOG_USE_STRUCTURED before including any
GLib header..."
- "[g_log_set_handler()] has no effect if structured logging is
enabled"

Hi Martin,
I might have the information you were asking for. (Please let me
know if this is not the necessary information, or if you need more
details.)
With a desktop file specifying three frames, there seem to be two
calls to `make-frame-on-display' (when the second and third frames
are created). Each call ultimately results in one of the reported
GTK warning messages.
Detailed backtraces at these two calls to `make-frame-on-display'
are attached.

Thanks. Please try now with a small init file containing a ‘make-frame’
call with the parameters from these attachments. For your first entry
I'd suggest to start with bisecting the parameter list in calls like

IIUC you saved two frames. Please try whether you can reproduce the

Unless Martin will be able to resolve the issue "properly", I guess
the only way of shutting up the warning is to use
g_log_set_writer_func to temporarily set the glib log writer function
to a dummy one that does nothing, then restore the original writer
function. That's gross, but what else can be done when you deal with
libraries which think they are smarter than you are?..
Thanks.

From `emacs -Q' the above call to `make-frame' causes the GTK
warning message.
After bisecting, I find that if I omit the last two lines, the GTK
warning is not emitted. Either or both of these two lines is
sufficient to produce the warning message:
$ src/emacs -Q --eval "(make-frame '((left . 0)))"
(emacs:13000): Gtk-WARNING **: gtk_window_parse_geometry() called on a window with no visible children; the window should be set up before gtk_window_parse_geometry() is called.
$ src/emacs -Q --eval "(make-frame '((top . 0)))"
(emacs:13008): Gtk-WARNING **: gtk_window_parse_geometry() called on a window with no visible children; the window should be set up before gtk_window_parse_geometry() is called.
$ src/emacs -Q --eval "(make-frame '((left . 0)(top . 0)))"
(emacs:13020): Gtk-WARNING **: gtk_window_parse_geometry() called on a window with no visible children; the window should be set up before gtk_window_parse_geometry() is called.
And finally,
$ src/emacs -Q --eval "(make-frame)"
produces no warning.

There is no warning message issued for the first/main Emacs frame.
So there is one less warning message than there are frames
restored from the desktop file. So in my previous examples I had
three frames and two warning messages. I hope that helps clarify
things.

[I'm sure your question is rhetorical, but if it weren't, at one time I
would have said the what could be done is to leave the world of
paternalistic proprietary software and use Free software instead! Sadly,
the paternalistic-proprietary-software thinking has infected Free
software and we increasingly see libraries and tools that do what they
think the user should want them to do, rather than flexibly doing what the
user asks them to do.]
But that does raise the possibly naive question:
Rather that trying to cover up the warning, can we not just do what the
library wants; is it impossible for us to call "gtk_widget_show_all() on
the contents and gtk_window_set_geometry_hints() on the window" before
calling gtk_window_parse_geometry()?

That's what I meant with "resolve the issue properly". Hopefully,
Martin will be able to rescue us from ourselves (and from glib's log
tyranny).

I still fail to understand what Jan had in mind when he eliminated the
gtk_window_move call from xg_set_geometry with PPosition set. We could
try to revert that change and see what happens.

IIUC most of what GTK's gometry parsing does is trying to avoid that a
frame appears offscreen. So it's not really about being smart. Emacs
is asking for it.

Thanks, I see now. For some reason I was convinced that the visibility
settings in frameset were involved.

Did you try? I suppose that gtk_widget_show_all would introduce some
additional flicker.

If no better idea comes up, I think we should indeed do that.

Troubles. IIUC we do all this trickery to make a new frame with the
left or top edge off-screen. This does make sense to me and does not
work here anyway.

The purpose of what? If you asked why people want to show a frame with
the top or left edge off-screen, then the major goup of clients might be
those who want to move the titlebar out of view.
Nothing against the use of (make-frame '((left . (+ -100)))) as long as
it's done within .emacs. It's a pain, however, when such idioms get
distributed in packages because then their authors will redirect users
to this list whenever a window manager refuses to comply.

Yes, that's what I asked.
If that's the reason, and we think doing that is legitimate, is there
any other solution but to shut up the warning?

I think that warning is legitimate. And even if I thought that what we
are doing is legitimate - xfwm would still refuse to put the top-left
corner of my new frame off-screen.

It's legitimate, but what we do as legitimate as well, right? And
emitting a warning in such use cases will only annoy users, right?

No, sorry, I didn't try. This is my first glimpse of any of the Emacs
window management code, and I'm not familiar with the GTK. Is there
documentation anywhere giving an overview of this area of Emacs? For
example, the "Commentary" section in frame.el is empty.
The question above was simply from a higher-level perspective. It looks
like we're not using the library in the way it is designed to be used,
so I assumed that there must be a reason why we are not. And I wondered
if that reason might not be worth reconsidering.
As for additional flicker, when I start Emacs things jump about like a
scalded cat, including a phantom random vertical scroll bar that often
makes a momentary appearance in the middle of my display. I've never
really understood why Emacs does this then other programs seem to manage
without such problems, but I've come to accept the behaviour -- after
all, it's only momentary while Emacs starts up -- and I don't think
additional flicker would necessary be much worse!

I'm not quite following this discussion. [Of course, it isn't
important that I follow it; however if you have time to elucidate,
I would much appreciate it.]
If we removed the arguably illegitimate chicanery, what
functionality, specifically, would be lost? Might it be achieved
in a more straightforward way?

The doc-string of gtk_window_parse_geometry says
* Note that for gtk_window_parse_geometry() to work as expected, it has
* to be called when the window has its “final” size, i.e. after calling
* gtk_widget_show_all() on the contents and gtk_window_set_geometry_hints()
* on the window.
and also
* Deprecated: 3.20: Geometry handling in GTK is deprecated.
If this were our doc-string, would you say that calling that function as
we do now is legitimate?
IIUC we call gtk_window_parse_geometry here because we cannot call
gtk_window_set_geometry_hints at this early stage because of
/* Don't set size hints during initialization; that apparently leads
to a race condition. See the thread at
http://lists.gnu.org/archive/html/emacs-devel/2008-10/msg00033.html */
if (NILP (Vafter_init_time)
|| !FRAME_GTK_OUTER_WIDGET (f)
|| FRAME_PARENT_FRAME (f))
return;
Aren't we desperately trying to shoot ourselves in the foot? If we
can't set hints realiably during initialization, we shouldn't try doing
it through some backdoor.

I'm sorry, I'm confused. Earlier you explained that we do that
because users want the ability of placing frames outside of the
visible area, so I concluded that the fact we allow that is because we
want to cater to such users. Now you seem to be saying that we
shouldn't cater to them? How to reconcile these two? Or am I missing
something?

It's not that we "shouldn't". IMO we "can't" (contrary to Windows).
Maybe before
commit 3e5fc571bd5a9bdbed786b43a7971c41f87c6ad8
Author: Chong Yidong <cyd@stupidchicken.com>
Date: Mon Oct 6 16:17:14 2008 +0000
(x_wm_set_size_hint): Return immediately if called during
initialization.
we were able to do so but I have no proof. If someone has a GTK build
older than that, please try whether something like
(make-frame
'((user-position . t)
(left . (+ -100))
(top . (+ -100))))
worked. Nowadays it can't IMO because gtk_window_parse_geometry has
/* we don't let you put a window offscreen; maybe some people would
* prefer to be able to, but it's kind of a bogus thing to do.
*/
if (y < 0)
y = 0;
if (x < 0)
x = 0;
Obviously, the window manager might also insist on putting the frame
on-screen (it does so here). But while I cannot put a GTK
override-redirect window off-screen initially, I can easily do that for
a Lucid override-redirect window.
Also
(let ((frame (make-frame)))
(set-frame-parameter frame 'left '(+ -100))
(set-frame-parameter frame 'top '(+ -100)))
works as intended here. But that's of little use when parsing default
geometry specifications. Well, we could synthesize that ...
So maybe we should do away with the gtk_window_parse_geometry call, wait
for people to holler and try to fix problems with gtk_window_move calls
followed by something like x_wm_set_size_hint (f, 0, true) if needed.
But I'm not overly optimistic and would like to hear the opinion of at
least one person with GTK skills first. Maybe everything I said here is
just silly.

Alternatively, make the current code which allows putting windows
off-screen be conditioned by a user option, by default off. Then
those who want that will have to deal with the GTK warnings.

That's a good summary of the problem. Try to use the following
definition of xg_set_geometry:
static void
xg_set_geometry (struct frame *f)
{
gtk_window_move (GTK_WINDOW (FRAME_GTK_OUTER_WIDGET (f)),
f->left_pos, f->top_pos);
}
I suppose it might break things like starting with a specified geometry
and a maximized frame and trying to demaximize the frame afterwards. It
might as well work.
The greatest problem in this area is always to find a solution that fits
(almost) all window managers and user preferences.

I have replaced the xg_set_geometry() in my Emacs with the one
above.
So far so good. (I haven't noticed any difference. (Aside from the
welcome elimination of the GTK warning message.)

I've tried closing and restarting Emacs with various frame /
window configurations (including "full screen" frames with the
title bar hidden), and the desktops restore just fine [1]. And
restoring / maximizing frames using the window decorations works
fine too.
[1] As has been happening for a while, buffers seem to be assigned
randomly (it seems) to the windows restored from the desktop file;
I'm still convinced that in the past on starting Emacs the windows
restored from the desktop file used to come up with the same
buffer in them as they had when the desktop file was saved.

Same here. One thing that doesn't work are negative offsets like in
emacs -Q -g 80x40-20-20. That's easy to fix elsewhere. If you don't
mind, continue using it for a while; maybe you detect something strange.

It would be nice if you were able to bisect that "while". The idea is
obviously that windows come up with their original buffers restored.

Here I can successfully position frames partially off the display
(using the mouse) but when they are restored from a desktop file,
they are moved slightly so that are fully on the display. (Perhaps
this is what you mean?) I don't see that this is necessarily bad
behaviour. (Others might (probably will!) disagree of course...)

Yes, I am using (and I will continue to use) your proposed
definition of `xg_set_geometry' from Message #122
(https://debbugs.gnu.org/cgi/bugreport.cgi?bug=25851#122).
I will keep my eye out for any oddities. So far, so good.
(Although, I should note that my usage of frames is very
tame/conservative; I tend to keep the same configuration of three
(sometimes four) full screen frames at all times.)

I considered reporting this bug a few months ago, but I couldn't
make enough sense of the behaviour I was seeing to write a
coherent report.
I tried again today, and I can no longer reproduce the problem!
Yet I saw it as recently as last week while I was preparing the
bug report for the current bug (bug#25851). Perhaps deleting old
desktop files has made the problem go away? I don't know.
But yes, if I start seeing the problem again, and if I have a
desktop file that I can use for testing, I will try to bisect
revisions to see when the behaviour was introduced.
Regards,
N.

The -20-20 are supposed to put the frame's right and lower edge at a
distance of 20 pixels from the right and bottom edge of the display.
This doesn't work any more because the corresponding calculations in
xg_set_geometry are not done any more. I moved them to x_set_offset
here.

Thinking about this twice - frameset should _not_ try to restore frame
positions by default. If people think they need it, they should modify
`frameset-filter-alist' appropriately, but by default this option should
be off. Introducing a gravity parameter might help but ISTR that most
window managers don't handle gravity correctly ...
> Once Emacs is up and running, creating new frames does not cause

Because IIRC restoring a frameset is the only case where Emacs tries to
position frames by default.
Anyway, I now introduced a variable `x-gtk-use-window-move' which, if
set, should avoid the problems with bug#25851 and bug#25943. These bugs
are strangely related because they can be fixed (at least here) by
calling gtk_window_move, a function which apparently is capable of
shelving a requested position and pass it on to the window manager when
we eventually ask for mapping the frame via gtk_widget_show_all.
Obviously, my fix might be silly so if anyone has a better idea please
speak up. The variable is off by default. If a sufficient number of
people confirm that it works, I'll set it on by default and will mark
this bug as done.
Note that the variable affects GTK builds only and should affect the
behavior of Emacs iff you set frame positions "programmatically" -
either via a geometry specification, a `left' parameter in the arguments
of `make-frame' or `set-frame-parameter(s)' or via `set-frame-position'.
Moving a frame by dragging its title bar is not affected. Indirectly,
however, all users of the desktop feature are. So please try it.
Many thanks for the forensics, martin

Could you try to investigate these flickering experiences somehow? Do
they occur only when you restore the desktop or are there more specific
occasions when you see them?

I have not been following this thread, so apologies if what
I say here does not seem to help.
I don't see (here) you give a reason (beyond the statement that
you have thought about it twice) why a desktop file should not
restore frame positions by default. (Maybe you gave a reason
prior to this post?)
As one user of multiple frames (and multiple desktops) I would
(naively perhaps) expect a desktop state to restore frames as
they were when they were saved, modulo anything that might be
strictly impossible or unfeasible to do.
If frame positions are not restored in general (again, modulo
any necessary exceptions that might exist) that would suggest
that there is little point in saving and restoring frames.
Size and position are among the most important attributes of a
frame, and if a user bothers to use multiple frames then it is
almost certainly the case that their sizes and positions are
important.

They occur only when Emacs starts up. They don't happen with `-Q'.
On the other hand, they still occur (to a much lesser extent) with
`--no-desktop' (in this case it seems (appearance-wise -- I didn't
look a the code) that the frame is displayed before the font size
is set and then after the font size is set, the frame changes
size).

I agree with Drew here. a user would reasonably expect that part
of the job of the desktop feature is restoring frames to their
former positions.

There is also, of course, the re-creation of all the buffers and
the re-assignment of the right buffers to the right windows on the
right frames. This is at least as important IMO.

Well, in my case, my display is small and all frames are
maximized, so the position of the frames is not important. So I
disagree with the "almost certainly", but otherwise I agree
completely.

ISTR that there was a long discussion about this when Juanma
implemented these features, so the current behavior is not just a
random choice on his part.
FWIW, I'm rather fond of the current behavior, since whenever I need
to restart Emacs, it recreates the precise frame arrangement I had
when I shut it down.

Jan who was responsible for the implementation of this in the past
advocated the use of Extended Window Manager Hints where you can read
(in the section about _NET_WM_FULL_PLACEMENT) that
Clients, when they detect that this hint is supported, SHOULD NOT
abuse or often even use PPosition and USPosition hints for requesting
placement.
Rationale: Window managers can often perform better placement (that
may be even configurable) for windows than the application. However at
the time of writing this it is problematic for Window managers to
decide when to use them because many applications abuse positioning
flags and/or provide unnecessary default positions.
So it's up to us to either go this direction or do our own placement. I
neither use desktop saving nor explicit window positioning so I have no
preference. But as this bug demonstrates, it seems that we may have to
choose one or the other eventually. Otherwise, we will sooner or later
end up in situations that are more troublesome than the present one.

It might be interesting to separate the issues involved here. I recall
the font size being one major trouble in this context but a good recipe
would be valuable even if we can't do anything about it.
Meanwhile please try my patch. If after a week or so you don't see any
troubles I intend to make it the default.

According to a comment in gtkwindow.c:
* If you are saving and restoring your application's window
* positions, you should know that it's impossible for applications to
* do this without getting it somewhat wrong because applications do
* not have sufficient knowledge of window manager state. The Correct
* Mechanism is to support the session management protocol (see the
* "GnomeClient" object in the GNOME libraries for example) and allow
* the window manager to save your window sizes and positions.
Just to explain where my doubts come from.

Hi Martin,

Sorry for the delay. I haven't used master for a while and it doesn't
like my init file. I've been spending my time on troubleshooting
that. But now I have things mostly up and running.
1. I am currently running master from earlier today which includes
your patch from the 23rd (commit
fe3af8d4f2a4cd67958f76d1b708e8a78e68cd4f) which I assume is the
one you want me to test?
2. I have not applied your proposed definition of
`xg_set_geometry' from Message #122
(https://debbugs.gnu.org/cgi/bugreport.cgi?bug=25851#122). [But I
still have that in my 25.2 rc2 Emacs, which is currently my
everyday Emacs.]
3. I have put
(setq x-gtk-use-window-move t)
in the working part of my init file [the rest of my init file --
about 10% of it -- is commented out right now].
4. In my desktop file I have three frames specified each with
a distinctive size and position.
The result is that:
- Frames are successfully restored to their former size and
position.
- No GTK warning messages are being emitted.
However:
- When I switch between frames using the window manager Alt-tab
window switching, there is a big flash almost every time when an
Emacs frame is displayed. I've never seen this problem before.
(Occasionally I've seen a single line of the display flicker while
scrolling, but I've never seen Emacs make the whole screen flash
like this before.)
[The flash is too fast to describe other than to say it is light
in colour and appears to be horizontal, almost as if there is a
white or grey highlight being applied randomly to about half the
lines in the frame and then turned off again.]
[This was after I'd maximized the three frames so that I could use
them, rather than when they were the smaller size at which they
were specified in the desktop file I tested with. I tried
restoring them down to their previous size and didn't see the
flash, then maximised them again and the flashing was back. I
suppose that the flashing might also be happening when they're
small but that my eye isn't fast enough to detect it; not sure.]
Of course this flashing might be unrelated, it might be due to a
change elsewhere in master.
The display antics at startup are slightly different but still
there. The sequence seems to be (with three frames in my desktop
file with distinctive sizes and positions):
a) A largish light-colour-scheme frame is displayed.
b) It shrinks but is still a light colour scheme. (Presumably my
default font is applied here.)
c) It changes to a dark colour scheme. (Presumably my colour
scheme is being applied here.)
d) It sits there for a bit with the various startup messages
appearing in the echo area.
e) It disappears and the three frames in my init file appear.
(Alternative explanation: It changes its size and position to that
of one of the frames in my init file, and the other two frames
from my init file are displayed.)
These antics are different from with Emacs 25 where I never see a
light-colour-scheme frame unless I start with `-Q'.
I hope this helps. Please let me know if you have further
questions for me.
N.

My reading of this text is that it says that applications should not
micromanage the positioning of windows. That makes sense. But placement
of restored windows at startup is not micromanagement in my opinion.
After all, it is putting windows back in the position that the Window
Manager placed them in the first place, or back in the position that the
user moved them to.

Could be the result of double-buffering implemented on master. What
was the date your previous master-derived version was built? If that
was before January, it could be before double-buffering was pushed.
Try disabling that via initial-frame-alist in your .emacs and see if
doing that helps.

I'm sure that Eli's suggestion is correct, so please inhibit double

I don't know what a colour scheme is. Please send me yours and I'll try
adding it to my .emacs to see which behavior it causes.
BTW I never thought about possible mergings of `initial-frame-alist' or
`default-frame-alist' and the parameter alists applied by desktop.

I suppose you mean "desktop" instead of "init" file here?

To get one aspect right: Do you see the light-colour-scheme frame also
when you don't restore the desktop - with one or three initial frames?
(And what else does master dislike about your init file?)

Right from our POV. But the window manager wouldn't know that these
frames are just "put back".
Note also that I do not necessarily agree with that text - it just might
explain the rationale of the windowing systems or window managers we use.

Yes, I haven't built master for a while, almost certainly not
since January.
But no it is not obviously the double-buffering IIUC. I evaluated:
(modify-frame-parameters nil '((inhibit-double-buffering . t)))
in each of the frames, but the flashing when switching between
them was not effected.

Earlier you said that:
[This was after I'd maximized the three frames so that I could use
them, rather than when they were the smaller size at which they
were specified in the desktop file I tested with. I tried
restoring them down to their previous size and didn't see the
flash, then maximised them again and the flashing was back. I
suppose that the flashing might also be happening when they're
small but that my eye isn't fast enough to detect it; not sure.]
Is the flashing reproducible with emacs -Q, two times C-x 5 2, <M-f10>
for each frame and then Alt-tabbing between the resulting frames? Or do
you need additional customizations?

It seems that this side problem of the flashing might not have
been directly related to Emacs.
There has been a lot of churn on my system with what feels like
very frequent kernel updates, as well as updates to the window
manager and to Xorg. The flashing problem started, and soon after
stopped, during this period.
Sorry for the noise.

This bug persists in the released version of Emacs 25.2 (built
from the tarball).
On the other hand, Master, checked out on 2017-04-27
(79c5ea9911a9aba7db0ba0e367e06507cee2fc02), does not exhibit the
bug.
I was unable to test the emacs-25 branch checked out on 2017-04-27
(784602b10506c50075aa9463891a47380ebea55f) because I haven't been
able to build it so far, however, since the log doesn't indicate
any substantive commits since the release of 25.2, it probably
still has the bug.

Try deleting aclocal.m4 first (there's no difference between the 25.2
tarball and emacs-25 though).

Sorry, Martin, I got sidetracked.
If your patch is in master but not the emacs-25 branch, then it
seems to work -- see my previous message to this bug thread.
Also I had no problems, over the past month or two, using your fix
to the definition of `xg_set_geometry' from Message #122
(https://debbugs.gnu.org/cgi/bugreport.cgi?bug=25851#122) which
also fixed the bug successfully in Emacs 25.2rc2.
Is there any possibility of your patch being cherry-picked to
emacs-25? Or is the plan to go to Emacs 26 next, rather Emacs
25.3?
Thanks.

Thanks Noam. This sorted itself with:
git clean -x --force
git reset --hard
Bit of a sledge hammer maybe; perhaps your surgical deletion of
emacs/aclocal.m4 would have worked too. Anyway, not sure what I'd
done wrong but everything is working again now.

No doubt obvious, but for completeness I wanted to report that the bug
is still present in current emacs-25 branch
(784602b10506c50075aa9463891a47380ebea55f ).

Currently there are no plans for Emacs 25.3. But doesn't your Emacs 25
already contain the patch? The only difference I made lately was to set
the default value of ‘x-gtk-use-window-move’ so all you have to do is to
make the last line of your xterm.c read
x_gtk_use_window_move = true;

No. Not if I understand correctly.
_My_ Emacs 25.2.rc2 is modified so that the entire body of
xg_set_geometry() is deleted and replaced by a call to
gtk_window_move(). This fixes the bug and did not produce any
adverse effects in six weeks of use (on my system at least).
My Emacs 25.2 is the stock release from the tarball. I don't know
if it contains any patch for this bug, but if it does that patch
does not appear to work.

The symbol `x_gtk_use_window_move' is not defined in the emacs-25
branch, only in master.

Sorry. I forgot to tell you to apply that change to your Emacs 25 back
then. Please remove any changes I proposed earlier and try to apply the
attached x_gtk_use_window_move.diff to your Emacs 25.
Thanks, martin

Thanks Martin,
I have just applied your x_gtk_use_window_move.diff patch to Emacs
25. That fixes the bug.
Can the patch be applied to the emacs-25 branch in case there is
ever an Emacs 25.3?
Thanks.
N.

This bug is fixed in the emacs-26 branch so I am closing it. Thank
you.
(Of course, if you think there is some subtlety in the bug that
has not been fully addressed (I don't think there is), please
reopen it.)
