Description Erik Quaeghebeur 2021-06-08 12:25:51 UTC 
In my logs, I find lots of repeated occurrences of the warning

<date> <time>	plasmashell	file:///usr/share/plasma/shells/org.kde.plasma.desktop/contents/views/Panel.qml:26:1: QML Panel: Binding loop detected for property "state"

As far as I can tell, there are no issues caused by this, but it is annoying when looking through the logs for other things.

Yeah. Fixing this has been on my to-do list.
Comment 2 Joe Breuer 2021-10-20 17:51:41 UTC 
I came across this in the context of another problem:

https://bugs.gentoo.org/818124

On my system, ksmserver-logout-greeter logs this specific diagnostic (Panel.qml: Binding loop detected for property "state") ONLY in the intermittently failing case.

Panel: Fix binding loop warning when switching between virtual desktops

containment.containmentDisplayHints should be set after state is
changed. This prevents a binding loop warning.
