-- Information about the crash:
I have 2 monitors, 1920x1080 (left) and 3840x2160 (primary, 150% scaling). I use wayland, so problem related to kwin_wayland. Sometimes one or all of my monitors could freeze and stop updating image. Usually it happens with left, when my cursor on primary. I tried to disconnect freezed monitor, but that action also freezes primary, and after ~15 seconds kwin crashes, all non-qt windows are killed.
When I do journalctl --user -b -p3 it shows a lot of this lines and last is dumped core info:
