Monitor Layout

After powering on monitors the shell is broken with Nvidia driver from 5.26.0 version. The panel is in the middle of the screen and one of the monitors won't wake up. Kscreen configuration is corrupted and must be removed in order to make the monitors behave correctly again.

STEPS TO REPRODUCE
1.  Wait until monitors are shut down due to energy savings (suspend or hibernation are not necessary)
2. Lock screen does not affect the bad behavior.
3. Move mouse or press any key in order to power on monitors.

OBSERVED RESULT
I have 3 monitors and one of them will not power on again. Kde panel appears in the middle of the screen and mouse click target acts as if graphics where in the original position. Kscreen config in '.local/share/kscreen' must be deleted in order to be able to reconfigure monitor layout after restart.


EXPECTED RESULT
After moving mouse or pressing any key monitor layout is correct after powering on and no graphic corruption appears. If lock screen is active, password is required in order to enter the session again.

I saw this related bug, but what I meant with this now is about broken shell. Will add some attachments in a while.
I just manually powered off monitors.
