When I create a new profile under "window rules" i cannot edit it, the section with all the settings simply does not open.
Using FreeBSD 12.1-STABLE
This gets displayed in the console if i click on the edit icon:
QQmlComponent: Component is not ready
"Error loading QML file.\n26: module \"org.kde.kitemmodels\" is not installed\n"
QCoreApplication::postEvent: Unexpected null receiver
I just fixed that missing component in kf5-kitemmodels, please update to kf5-kitemmodels-5.71.0_1
Fixed, thank you!
