For some time I see the following messages in my logs:
Lokal2021:Jan 12 14:46:54 samd org.kde.LogoutPrompt[1061376]: Cyclic dependency detected between "file:///usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/kirigami.2/styles/org.kde.desktop.plasma/Units.qml" and "file:///usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/kirigami.2/styles/org.kde.desktop.plasma/Units.qml"

I haven't experienced any user visual problems due to this.

If this is harmless and cannot be (easily) resolved, could you add a
logcheck pattern to filter this out?

Thanks!
