SUMMARY
Almost every day kwin_wayland crashes for me. I do not know what reproduces it,
it happened while I was using the computer, while it was idle, at day,
overnight, etc..
I have seen it on two different computers:
A HP desktop with a single HDMI monitor and a DisplayPort drawing tablet and
old Radeon RX 550 GPU
Lenovo X1 gen 6 with Intel GPU

The crash always kills all my wayland apps except Konsole. Krita and Firefox
crash in 100% cases where this happens.
The traceback is always the same:

I will attach the full coredump info file too.
