Created attachment 146677 [details] Broken plasma decorations SUMMARY The window management and decorations break sometimes when dragging around windows. I'm not 100% sure what causes it yet, but I suspect it to be either dragging across screens, or tiling it to an edge. This is only happening since the the 5.24.0 update. STEPS TO REPRODUCE 1. Drag a window around, possibly attempt to tile it 2. Suddenly X11 becomes unresponsive 3. X11 unfreezes, but is barely usable OBSERVED RESULT Windows become selectable again after X11 unfreezes, but it is not possible to drag them around. In addition to that, the mouse is offset by at least 100px, and all Plasma decorations become blackened (see screenshot). SOFTWARE/OS VERSIONS Linux: 5.16.8 KDE Plasma Version: 5.24.0 KDE Frameworks Version: 5.90.0 Qt Version: 5.15.2
Could you please describe the freeze more? Do other windows respond to clicks or keyboard input? Does task switcher work? Do global shortcuts work? Does kwin start consuming CPU a lot?

Do global shortcuts work? > Does kwin start consuming CPU a lot? The windows do respond to mouse input, but because the effective mouse position is offset it's hard to interact with anything properly. I didn't test KB input, but I assume it still works as well. The task switcher works, but is darkened like the system tray dropdown plasmoid. My shortcut for krunner was still working, that's the only one I tried. Didn't notice any high CPU spikes when I switched to a TTY and checked htop. I'll try to hopefully get some log output once I manage to reproduce it.

Created attachment 147657 [details] snippet of journalctl output after bug occured Just happened again, and I managed to get some logs this time. Also, it does seem to affect other windows that utilize OpenGL, like Alacritty for example. I do think it's related to Steam doing something weird, as it seems to happen when tiling the Steam window.
It happened at around 22:45, which is also where some OpenGL errors were starting to show up in the logs
I haven't encountered this issue in quite a while, so at this point I just assume it was a weird interaction with a specific version of Steam and X11. And since I'm no longer using X11 I wouldn't be able to retest this either way.
