Description Bernhard Schertler 2022-11-10 05:41:11 UTC

STEPS TO REPRODUCE
1. Connect at least 2 screens (in this case laptop + 2 screens)
2. Set one of the screens as primary, but move the taskbar to another screen
3. Disconnect secondary screen(s)

OBSERVED RESULT
Taskbar running as normal, but not being displayed on the only connected display. Restarting does not fix the issue, only fix I have found is reconnecting the external display(s) and moving the taskbar to the primary screen again.

EXPECTED RESULT
Taskbar being visible on the only connected display (laptop screen)
