SUMMARY
I have a laptop with a 2nd screen attached via HDMI. When the 2nd screen is
turned on, all maximized windows switch to the 2nd screen. Minimized maximized
windows also switch screens. Unmaximized windows do not switch screens.
STEPS TO REPRODUCE
1. Move all maximized windows to laptop screen
2. Turn 2nd screen off
3. Turn 2nd screen on
OBSERVED RESULT
All maximized windows switch to the 2nd screen
EXPECTED RESULT
Windows that were originally on the laptop screen should stay on the laptop
screen when the 2nd screen is turned on

not happen. This could be caused by a recent change to KWin or the result of
switching to new hardware.
