Description locutusofborg 2021-12-13 23:47:32 UTC

I'm running Garuda Dragonized Blackarch KDE and I'm getting the below. It happens when I rightclick a titlebar and select "Configure Special Application Settings".  Any way to fix this?

Kwin_rules_dialog closed unexpectedly  Please report this error to help improve this software.

Mmm.. I wouldn't know how to debug this. It seems like there is a recursion problem on QtWidgets domain, which is driven by KCMultiDialog (from kcmutils package). Specific to this KCM there should be mostly QML code acting. Might there be a conflict of versions due to packaging between kcmutils and kwin?

Does the crash also happens when launching `kcmshell5 kcm_kwinrules`?
And opening the corresponding `Window Rules` section in System Settings?

This bug was reported against an outdated version of KWin. We have made many changes since the. 
If the issue persists in newer versions can you reopen the bug report updating the version number.
