Description lod 2022-05-13 08:42:00 UTC

The problem got introduced by plasma 5.24.5 (Wayland session). I've 2 displays right now, a dell and an iiyama (primary). After waking my pc up from suspend, plasma recognizes both displays as dell, and they are oriented like my secondary display, showing the same. I've to restart to get it working normally again.
My dell wakes up faster, I think that's why it's "cloned".

This is how it's supposed to look like https://i.imgur.com/d7hutTa.png
This is what I get after suspend (pulled them apart to show both) https://i.imgur.com/GJfxbDL.png

Going back to plasma 5.24.4 fixes the issue.
