unexpected icon behaviour

SUMMARY
Icons on desktop get positioned behind task manager after switching display off and on again. This also breaks the view of virtual desktops in overview. Overview no longer displays open windows on wallpaper for virtual desktops, but only grey instead.

STEPS TO REPRODUCE
1. a vertical task manager
2. duplicating main display to a second monitor
3. switching main display off and on again

OBSERVED RESULT
Virtual desktops no longer show a preview on overview.
Icons get positioned behind task manager.

EXPECTED RESULT
icon positioning staying the same
virtual desktop previews staying the same

Is your panel using "Windows can cover" mode, or something else?

didn't see an option for windows can cover but I think it's the "always visible", so no. Windows do not cover it.

I hope I'm not wasting anyones time but I think having a second monitor set up as replica of main monitor and then turning main monitor off and on again is important to reproducing this bug.
Comment 9 Nate Graham 2025-05-13 16:13:08 UTC 
That seems very relevant indeed. Can you ever reproduce the issue without any monitors replicating others?

Seems to happen only when another monitor is set as a replica now that I tested it. Both consequences are really annoying for the desktop experience. I didn't file two reports for the bugs since it seems to be the replica + turning monitor off and on from the power button that causes both.

Thanks! There were improvements to replication in Plasma 6.4, and I can't reproduce the issue there. So it looks like this has been fixed!
