https://bugs.kde.org/show_bug.cgi?id=493142 --- Comment #19 from postix --- Unless it's now fixed in 6.4.2 for your, I believe it would make sense to get some profiling with https://github.com/KDAB/hotspot?tab=readme-ov-file#using You would record the kwin_wayland process with perf, while it's consuming 100% cpu and study afterwards the flamegraph in hotspot, to see, where it consumes most cycles. Hopefully, this would give a good clue. -- You are receiving this mail because: You are watching all bug changes.

I've also tried to do the same for mesa however the build is failing - I will pursue if it ends up being necessary as well.

It's only possible to recover by ssh-ing into the machine and kill the kwin_wayland process from there. -- You are receiving this mail because: You are watching all bug changes.
