Created attachment 172053 [details] A relevant part of journal SUMMARY When I wanted to ALT+TAB out of a gamescope window, the whole desktop hanged for around 10-15 secs (even the mouse). I could not change VT either. I could trigger this with ALT+TAB after this consistently, and with hovering over on taskbar items (to show the hovered over window). Switching apps on taskbar via the mouse (without letting the hover trigger) didn't cause a hang. Also I noticed that on one of my monitors the framerate seemed normal (144Hz monitor), but on the other one (60 Hz monitor) it was low, 20-30 ish. The hang did not affect audio. There is some Pageflip timed out errors in the journal, so it might be some kind of driver/kernel issue. kwin used around 60% CPU according to htop (so it should be a single core) The system had an uptime of 5 days without any problem, and this didn't happen before either. Rebooting solved it, and now I can't make kwin go into this state anymore. Also, I'm not sure if I selected the correct component STEPS TO REPRODUCE I can't reproduce it now. But I did the following that triggered it somehow: 1. Start a game in gamescope with forced mouse capture 2. The given window is smaller than the screen resolution, however the mouse is grabbed. Try to resize the window (it won't let you). Then try to maximize the window 3. Press ALT+TAB OBSERVED RESULT Desktop hangs for 10-15 secs, and subsequent ALT+TABs hang it too. EXPECTED RESULT Desktop shouldn't hang.

ADDITIONAL INFORMATION I have some perf output, but it's too big for an attachment and I'm not sure how I should cut some of it out

Apparently there is an open issue there that seems to be the same as mine, I'll leave the link here for anyone that finds this bug report: https://gitlab.freedesktop.org/drm/amd/-/issues/3304
