I observe a similar problem. The problem is reproduced stably.

If a wine game is running, (or a native 3d game) is launched in full screen
mode. When changing the Alt + Tab window, the kde environment freezes:
1 The taskbar stops showing up-to-date information (does not show the wine game
process)
2 The clock on the taskbar does not update, shows the time at the time the game
started. It seems that everything in the taskbar stops updating.

If there is a crash during the wine game, then exactly what is written in the
description of the bug happens. The screen partially stops updating, and mouse
movement is not visible. The mouse is visible only with the active window
switch in a small rectangle.

I guess that the problem is somehow related to the restoration of 3d context.
In xfce, this problem does not reproduce.

Games to reproduce:
1) kde does not update when alt + tab can be easily checked by installing the
game:
https://store.steampowered.com/app/203770/Crusader_Kings_II/
2) the same as in paragraph 1, plus the disappearance of the mouse, and what is
written in the description of the bug can be checked by running the game under
wine https://london2038.com/quickstart-guide/

This is the first time I'm writing a bug in KDE, correct me if I wrote the
wrong way. If you need additional information, I will provide it.

The mouse still moves. The appearance of the situation varies. Usually the
application is half-minimized. Other times the application appears fullscreen
and other fully minimized. The application seems to be partially responding to
mouse clicks (some sounds clicking certain items), but the screen does not
change at all.

Pressing alt+Shift+F12 after the freeze does not help.


The output of qdbus org.kde.KWin /KWin supportInformation before the freeze (it
is impossible after it):
KWin Support Information:
The following information should be used when requesting support on e.g.
http://forum.kde.org.
It provides information about the currently running instance, which options are
used,
what OpenGL driver and which effects are running.
Please post the information provided underneath this introductory text to a

please provide the output of:
qdbus org.kde.KWin /KWin supportInformation

please describe the "freeze" situation better. Is the mouse still moving? Can
you press alt+Shift+F12? If yes, does that fix the situation?
