Hi,
Vertico version 1.7, version 1.3 has also been tested, is incompatible
with the changes made by the commit -
caea0c1649d1df96b811c1388fde396e66bc356b. This commit was found via
git bisect.
To reproduce:
1. Run emacs -Q
2. M-x load-library vertico RET
3. M-x vertico-mode RET
4. Set a large font, the following is suitable for my 13 inch monitor:
(set-face-attribute 'default nil :family "monospace" :height 440)
5. Call M-x
Emacs should freeze, sometimes you can unfreeze it with a few presses
of C-g

Thanks, but why do you think the bug is in Emacs and not in vertico?
The fact that you can unfreeze Emacs with C-g indicates that some Lisp
is involved in what probably is an infloop. At the very least, could
you please catch a Lisp backtrace when you type C-g, so that we could
see what Lisp is involved? Also, what exactly does vertico do with
resizing the mini-window, and what should be the value of
resize-mini-windows for reproducing this issue.

Also, if at all possible, please attempt to interrupt Emacs while it is
so frozen under GDB until you have collected several unique backtraces
containing entries for `redisplay_internal', and post them here.

resize-mini-windows is set to default ‘grow-only’
All vertico customs are also default.
I couldn’t reproduce it any other way, but it seemed to me that there
might be some problems with the redisplay.
I couldn't get a backtrace because if you set the debug-on-quit to t,
then C-g no longer helps. 2 screenshots in the attachment, but the
backtrace is only partially visible.
I'm not very familiar with gdb, I'll look into the matter and attach the
backtraces.

No backtrace yet, but I found another reproducer without vertico, all
used packages are from Emacs core.
Configured using:

3. M-x test-dispatch
4. Try playing with the parameters test1, test2, test3, test4. At the
same time you can put Emacs into full screen mode and back into windowed
mode, where it will occupy half of the screen. Initially, calling the
parameters test1, test2, test3, test4 in the transient window will be
delayed and everything can be canceled with C-g, after a few repetitions
Emacs hangs completely.

Thanks, but I don't understand what to do after "m-x test-dispatch".
Please tell in more details what you mean in Step 4, in terms of what
I need to type after "M-x test-dispatch". (I tried several things,
but couldn't get any interesting effects, let alone a hang.)

I run test-dispatch, for example I press "r", which calls the
minibuffer. At this point, Emacs is already starting to freeze for me; if
I change the full-screen to windowed mode several times, everything gets
worse. If nothing happens after pressing "r" you can try other bound
letters.
In fact, I can call commands through the tool-bar or menu-bar, but
everything that is displayed in the window or minibuffer does not
change. Was able to switch to the *Bactrace* buffer and save it via the
menu bar.
Bactrace is attached.

I tried all the letters, and didn't see any hangs.
Maybe this only happens in a GTK build with Cairo.
You say "set a large font", but running your recipe I don't see any
large fonts, except in the help-echo tooltips. Maybe that's why I
cannot see any problems. Perhaps the problem is with the
set-face-attribute part of the recipe, in that it doesn't produce the
same effect on my system as on yours?

What you "eval-buffer", is the Emacs frame visible in its entirety on
the screen, or are parts of it hidden because the font is too large?
I tried different fonts and different sizes, and as long as I can see
the frame on the screen, I don't see any hangs. Maybe this only
happens with pathologically large fonts, with which only a small part
of the frame can be seen, but if so, why is this situation
interesting?

with (set-face-attribute 'default nil :family "monospace" :height 440)
the result is the following:
--8<---------------cut here---------------start------------->8---
(list (window-height) (window-width)) => (13 53)
C-u C-x = (what-cursor-position) =>
display: by this font (glyph code):
ftcrhb:- -Go Mono-regular-normal-normal-*-58-*-*-*-m-0-iso10646-1 (#x37)
--8<---------------cut here---------------end--------------->8---
I think this is still a reasonable size. I usually have my font height
set to 240, and recently I noticed that vertico was starting to lag at
this setting. Researching further, I found that the larger the font, the
more obvious the hang, and I also found the commit after which it all
started. I think that there is a bug here, but we need to investigate it
further and check it without pgtk on X.

This situation works well here, it doesn't hang.

Could someone please reproduce and investigate? Po Lu, any
suggestions or ideas?

Alexandr, please send me an archive containing the font files for "Go
Mono", and I'll try to reproduce.

I also checked the following fonts: Iosevka, Liberation Mono, DejaVu
Sans Mono, the behavior is the same.
