MESA 22.2 Regression Causes Kwin Crashes (Fix Available)

[Gunter Ohrner]

MESA 22.2 contains a malfunction which causes kwin to exit regularly / frequently, leaving the system without window management.

This is a regression compared to MESA 22.1 and fixed again in MESA 22.3.

See following MESA bug:

* https://gitlab.freedesktop.org/mesa/mesa/-/issues/7674
* just for reference, corresponding KDE Bugtracker entry: https://bugs.kde.org/show_bug.cgi?id=461316

Maybe the fix could be backported?

It currently is something between inconvenient (for very technically savy users) and rendering the system unusable (for less technically savy users - suddenly, Window Management will be gone and switching windows, accessing panels, and controlling most applications even if they are in foreground at the time of a crash become impossible).
