SUMMARY Everytime I change some settings related to window manager, whole Plasma on Wayland freezes. For example when I change window rules or when I change compositor settings or when I change window decorations. All I need to do is click save and whole screen freezes. Music continues to play, so system is not dead. Also pressing Ctrl+Alt+Backspace works. I suspect problem might be with reloading window manager. I set severity to critical since it renders my computer unusable and I loose all my work. STEPS TO REPRODUCE 1. Click any window 2. Add window rules 3. Click save OBSERVED RESULT Whole Plasma freezes. EXPECTED RESULT Settings are saved and I can continue to work. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Manjaro Stable KDE Plasma Version: 5.18.5 KDE Frameworks Version: 5.70.0 Qt Version: 5.14.2 ADDITIONAL INFORMATION Is there any extra information I can provide?
I can confirm this bug, just as elman@seznam.cz described. SOFTWARE/OS VERSIONS Linux/KDE Plasma: OpenSuSE Leap 15.2 KDE Plasma Version: 5.20.3 KDE Frameworks Version: 5.76.0 Qt Version: 5.15.1
I cannot reproduce with current git master. Can someone who is able to reproduce the issue provide more detailed steps I can follow?
I retested all 3 issues: - when I change window rules - when I change compositor settings - when I change window decorations on Plasma 5.21.2 and can't reproduce any of them. Hopefully they are all fixed.
Please re-open this bug report if this issue comes back.
Sorry, but I have to reopen it. In my up-to-date openSUSE 15.2 it still happens. If I change window decorations, my Wayland session still freezes, just as it did before. This is my system: Operating System: openSUSE Leap 15.2 KDE Plasma Version: 5.21.2 KDE Frameworks Version: 5.79.0 Qt Version: 5.15.2 I'll upload a video (taken with my phone) so you can see it.
Here's the video: https://www.dropbox.com/s/9xfhn596z02cftn/Bug%20421829%20-%20Wayland%20freezing.mp4?dl=0 At the beginning you can see my system info. Then, when I change the window decorations, everything freezes, the countdown stops, and I can't click on anything anymore.
Happens for me on 5.22.3 as well, 100% reproducible. What's needed for diagnosis? I can't find anything relevant in the logs.

As requested by Vlad, I checked pendingFrameCount of the RenderLoop instance, and it's indeed stuck at 1. drmHandleEvent is never called FWICT.
I just checked on Plasma 5.22.4 / KF 5.85.0 / Qt 5.12.2 / Arch Linux and whole desktop froze when I tried to add window rule (position and size). So bug still manifests.
Can you still reproduce it with some more recent version of Plasma?
I can't reproduce it anymore in an updated system: Operating System: openSUSE Leap 15.3 KDE Plasma Version: 5.25.3 KDE Frameworks Version: 5.96.0 Qt Version: 5.15.5
I also can't reproduce it on fully updated Manjaro Unstable and Arch. Both have Plasma 5.25.3, KF 5.96.0 and Qt 5.15.5+kde+r174-1.
Ok cool, I guess it got fixed.
