Subject: 31.0.50; menu-bar-mode unexpectedly shrinks frame substantially
Date: Tue, 11 Feb 2025 20:48:41 +0100

To reproduce this issue, please invoke Emacs with:

    $ emacs -Q --eval "(while t (menu-bar-mode (if menu-bar-mode 0 1)) (redisplay))"

Within a few seconds of running this, I unexpectedly see the frame
getting smaller and smaller.

With earlier Emacs versions, the frame unexpectedly becomes
substantially larger within a few minutes of running it.

All the best,
Markus

I cannot reproduce this on MS-Windows.

Martin, any comments, thoughts, or suggestions?

The frame keeps shrinking and expanding by one line as expected.

What happens when you evaluate

(setopt frame-inhibit-implied-resize '(tab-bar-lines menu-bar-lines))

before triggering that loop?  If you want to run it from the command line,
use

 --eval "(progn (setopt frame-inhibit-implied-resize '(tab-bar-lines menu-bar-lines)) (while t (menu-bar-mode (if menu-bar-mode 0 1)) (redisplay)))"

Thanks, martin

This yields exactly the behaviour I would expect from repeatedly
enabling and disabling menu-bar-mode, i.e.: no changes of frame size
even after many repetitions.

Thank you and all the best,
Markus

no further comments, so I presume the issue is resolved, and I'm
closing this bug.
