Works without problems for me with emacs 27.2.

It may be due to a rounding problem with the WM_NORMAL_HINTS property?
It may be related to the dimensions of the font? Which font? How to set it?

Provide the output of icesh spy on the emacs window while the bug occurs.
That records changes in dimensions and changes in the X11 window properties.

Do they have the same problem with changing fonts with Ctrl-plus and Ctrl-minus in other apps like Firefox.

Do they have the same problem with changing fonts with Ctrl-plus and Ctrl-minus in other apps like Firefox.

No, I don't have the same problem when changing font in Emacs by using single buffer modification, only when using global modification.

In that spy output there is:

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.

In my emacs, with either global-text-scale-mode enabled or disabled, my icesh spy always has this:

WM_NORMAL_HINTS MinSize(0,0) Base(0,0)

And no problem occurs. So unfortunately I can't repeat your experiment.
If I could get the same WM_NORMAL_HINTS behavior I could look deeper into this.

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.

This was released in 3.3.1 two weeks ago. Does it work to your satisfaction?

@gnusupport

I cannot even know. I am using icewm 3.3.1-1, and Emacs developers also corrected the behavior, so from both sides it was corrected. I think your correction is not even necessary if you say IceWM does it by standard.

To test it, I would need to go back to previous Emacs version. I think it is not necessary.

Issue shall be closed.

I just hope that it does not affect IceWM negatively.
