Bug 448798

Application: systemsettings (5.24.80)

Qt Version: 5.15.2
Frameworks Version: 5.91.0
Operating System: Linux 5.16.0-1-default x86_64
Windowing System: Wayland
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.24.80 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
Previously this was happening only when trying to change the window decoration, as I was using another Widget Style forked from breeze called Lightly that made the desktop environment relatively stable. Upon changing back to Breeze, plasmashell would crash, dolphin would also crash if a context menu is opened anywhere, even DrKonqi would crash if it tries to troubleshoot any of those apps and face the same problem. This forced me to continue using forks of Breeze to continue using my computer. I've been using Lightly and ClassiK as replacements of Breeze for some time now and compiling them from source. I also used LightlyShaders to get corners rounded on X11 but this is also happening on Wayland. It's been years I've been running openSUSE Tumbleweed on this machine and only now it presented any problem of the kind with Plasma while the rest of the system works just perfectly, so I'd rather not have to reinstall the operating system if it means to get Breeze working again.

Packages are being supplied by KDE Unstable Repos for openSUSE Tumbleweed. I plan to move to kdesrc-build in the future but for now, it is where I got everything so far. A dist upgrade was done a few hours prior to submitting this bug, so everything is up to date regarding the Unstable Repos.

- Unusual behavior I noticed:
The scaling offered by KWin breeze did not scale the window decorations, so they remained the previous size when scaling to 75% in my case, making it way too big and placing elements in weird places.

The crash can be reproduced every time.
