Recent kwin_wayland crashes from coredumpctl and info from the latest

SUMMARY

Every 1-3 days since upgrading to Plasma 6 kwin_wayland crashes with a segfault. It happens with or without user activity, at seemingly random times of the day or night -- though in several cases the crashes corresponded to first usages in the morning. This is an issue new to Plasma 6 -- no such crashes occurred previously on 5.27. The recovery process does reinstate any running KDE apps, but obviously any others are killed.

STEPS TO REPRODUCE
1. Boot the machine.
2.  Wait.

OBSERVED RESULT

Eventual segfault and crash, leading to the forcible closure of all non-KDE apps followed by kwin recovery.

EXPECTED RESULT

No segfaults.

Thanks for your report, unfortunately there is nothing in that backtrace that is actionable.

In the backtrace, we just have some boilerplate showing that it is /going/ to dispatch something to kwin code, then the rest is missing.

Either try to ensure all kwin debug symbols are present and get a new trace, or we can wait it out and hope another report fixes the same issue
