SUMMARY
Some windows automatically switching screens on unlock! 

I am using latest version of KDE (I think it is 6.1.1) on Garuda Linux (which
is almost the same as Archlinux).

I have an external monitor connected to my laptop. The monitor is labelled as
primary display and the laptop as secondary display. Generally, when I log back
in from lock screen, my window placements go haywire. That is, many windows
which are open in primary screen (monitor) will be moved to secondary (laptop
screen) and will be maximised. This happens specifically for Dolphin, Konsole,
KTorrent, Kate. Maybe others too, but I’ve observed these. Other windows like
Chromium, VSCode, etc do not have this issue.
This does not happen always, but whenever I'm away from my desktop for longer
(longer than 10-15 minutes). If I lock my desktop and unlock within a short
period, everything is fine.

I am running on Wayland with support for XWayland. Is it possible that this
issue is happening for windows that run on Wayland and not XWayland?


STEPS TO REPRODUCE
1. Have multiple displays (external monitor connected to laptop). In my case,
the external monitor is primary display and laptop screen secondary.
2. Open multiple applications, some that run on Wayland and X11 apps. In my
case, I have several Chromium windows, VSCode, Dolphin, Konsole, Kate,
KTorrent, etc. Open them in primary display (external monitor).
3. Lock the desktop.
4. Unlock the desktop after 15-20 minutes or even better resume from sleep and
unlock the desktop.

OBSERVED RESULT
Some windows - Dolphin, Kate, KTorrent, Konsole, etc have moved to secondary
display (laptop screen) and are maximised (even though some were not maximised
earlier). 
Other windows like Chromium, VSCode, etc are right where I left them.

EXPECTED RESULT
All windows should be in the same position, i.e., same screen, same virtual
desktop and same location where it was present before the machine was locked or
put to sleep.
