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.

I have narrowed it down to wayland being the problem. Windows of apps that run on X11/XWayland works fine. But wayland apps will frequently move to the second screen (laptop screen instead of external monitor) and will be maximised after coming back from lock screen (again, not immediately, but after a while of being locked).
I ran xlsclients command to determine which windows/apps were running on X11/Xwayland. I figured out Chromium was one such app. After I changed the flags to launch it with Wayland, Chromium also started behaving the same way! ALL Chromium windows would be moved from primary external display to secondary laptop screen and will be maximised!

One more update. Today, I had not locked my screen, but left my desk unattended for 10 minutes. ALL the chromium windows (running on wayland) were automatically moved from external monitor (primary display) to my laptop display (secondary)!  
So, this happens not only when the machine is locked, but also when it is left unattended without locking. If the desktop is being used, then there is no problem.

Here are the journalctl logs for this period:
