Created attachment 159987 [details] kwin_wayland backtrace SUMMARY kwin_wayland randomly crashes when (I believe) attempting to work with the clipboard, but cannot say for sure. It certainly appeared random, and I can say I certainly saw it happen at least twice. I have attached a backtrace of the latest crash. STEPS TO REPRODUCE 1. Start a plasmashell session 2. Do things on the desktop 3. Crash OBSERVED RESULT kwin_wayland crashes. EXPECTED RESULT kwin_wayland shouldn't crash when attempting to use the clipboard.

Git commit e93adbee074a2527e83851a1690440ce53aa021b by David Edmundson. Committed on 01/07/2023 at 11:47. Pushed by davidedmundson into branch 'master'. xwayland: Guard against xwyayland connection closing in input spy The event spy is removed when xwayland closed, but it's based on the process not the wayland socket, so it can be temporarily out of sync. There were no guards for the connection being null. M +4 -3 src/xwayland/xwayland.cpp https://invent.kde.org/plasma/kwin/-/commit/e93adbee074a2527e83851a1690440ce53aa021b
