Description Jiri Slaby 2022-04-04 08:45:39 UTC 
This is maybe a dup of bug 452247?

SUMMARY
When I unplug an external monitor connected via Thunderbolt and replug it, all windows switch "their" monitor. I.e. if a window was on the laptop monitor, it is now on the external one and vice versa.

STEPS TO REPRODUCE
1. plug in an external monitor
2. move some windows there
3. unplug + replug

OBSERVED RESULT
The windows are on the opposite monitors.

EXPECTED RESULT
The window's monitor should be preserved.

Yep looks like it.

Notably this is not an issue with the X11-specific code to position some KDE windows since you're on Wayland.
