bug#46155: 28.0.50; Regression: buffer contents flicker on macOS frames when

[Aaron Jensen]

From emacs -Q:

(dotimes (n 10)
  (set-frame-parameter nil 'width (+ 80 n))
  (sit-for 0.1))

This was previously fixed in bug#30699

I don't know if it was reverted at some point and I didn't notice, or it
was started flickering again after Alan's recent (fantastic) performance
improvements.

This reproduces on master (non-native-comp) as of ac102bb966 as well.

Apple deprecated the functions we were using to block screen drawing.

It's possible we can have a neater work-around now since we're drawing

Well... I tried something ridiculous and it appears to work...

I suspect forcing redisplay this way within the NS run loop is bad
form, but it appears to work.

Awesome, it works for me. It also fixes an issue I've had when
launching Emacs and resizing it and it remaining blank for an extended
period of time (probably while it's busy, but it's still rather
unsightly)

I'll give it a shot for a while and report back.

Mini frame only buffers still flicker on resize, see
https://github.com/muffinmad/emacs-mini-frame/issues/31

Repro (thanks to Andrii Kolomoiets):

emacs -Q
M-: (setq resize-mini-frames t)
M-: (make-frame '((minibuffer . only)))
M-x

Where do you type those letters?  Into the normal frame?

I suppose 'fit-frame-to-buffer' is to blame here.  What happens when you
set 'resize-mini-frames' to 'ignore?  Some other function that resizes
the frame more conservatively or sporadically?

No, into the minibuffer-only frame.  After `make-frame` the
minibuffer-only frame became focused and accept input.

The minibuffer-only frame doesn't resized and the text is not flicker.

I've set the `resize-mini-frames` to this function:

    (defun test/resize (frame)
      (modify-frame-parameters
       frame `((width . ,(+ 80 (random 20))))))

After each letter typed, the minibuffer-only frame is resized several
times.  The text is not visible during resize.

Works here on Debian without problems, the minibuffer-only frame expands
by one character as expected.  I still doubt that this is an NS problem.

Can you try with a function that explicitly keeps the height constant -
i.e., calls 'fit-frame-to-buffer' with ONLY set to 'horizontally'.

But I see that 'test/resize' does that already.  Is that function called
more than once each time you type a letter?

In case it matters, the background here is that after a resize Cocoa
doesn't retain the contents of the frame, but since the frame is
garbaged Emacs won't draw anything until redisplay is completed, but
Cocoa won't wait for redisplay, so we end up with a brief blank frame.

The patch Aaron and Andrii are using calls redisplay() just before the
frame is drawn, but only if it is garbaged.

My assumption is that something in this repro recipe is causing
redisplay to refuse to draw the frame until something else has
occurred. I've no idea what that could be and haven't investigated
yet.

Yes.  Almost each time I type or delete a letter.  Same on recent master
version under X (Gnome).  After typing C-g that function is called even
more times.

I see from a subsequent email that Andrii isn't using the NS port, so
that bit of my message is wrong.

Sorry for kind of misleading you.  I indeed use NS port. The receipt for
minibuffer-only frame flickering was made on nearly recent master
version with your patch applied.  (I must say resizing and fullscreen
transition looks awesome now, thanks!)

I used GTK port under X in the VirtualBox to test the issue with the
minibuffer-only frame resized more than once even if the text is not
changed.

Hmmm ... When I load with emacs -Q


(setq default-frame-alist '((minibuffer . nil)))

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

(defvar foo 0)

(defun foo (frame)
   (setq foo (1+ foo))
   (fit-frame-to-buffer frame))

(setq resize-mini-frames 'foo)


and leave Emacs alone for a while, 'foo' has increased by about 30 (I'd
attribute 20 of them to 'blink-cursor-mode').  So 'fit-frame-to-buffer'
apparently does get called way too often.  But if I now evaluate

(frame--size-history (window-frame (minibuffer-window)))

and look into the *frame-size-history* buffer, I see no excessive number
of calls to resize the frame's window here.  Maybe things are different
under Gnome or NS.

Ah, OK. I guess it probably is exclusive to NS then.

The obvious solution IMO is to retain a copy of the old frame contents
and draw them in after resizing, before we try calling redisplay().

On the other hand, it would be nice to know why redisplay() isn't
drawing anything...

inhibit-redisplay appears to be t when miniframes are asked to resize.
Could that be related? I tried letting it to nil and that didn't help.

It also happens that setting the resize to happen via run-with-timer
fixes the flicker:
https://github.com/muffinmad/emacs-mini-frame/pull/32/files#diff-8289c4c5300044ca6d7f9f6f60067a1b5e0d61b6ad0b58720a7c694662ea13abR207

Unfortunately, that prevents resizing when displaying a prompt like
`yes-or-no-p`.

The other different thing about the minibuffer resizing is it all
happens within `read-from-minibuffer`
