SUMMARY
Note: this might belong in KScreen instead, I'm not sure.

When I have both my external monitor and laptop monitor enabled, and switch to the external screen only (by meta+p), the windows on my laptop monitor stay there and are inaccessible. Only when I disable the external monitor first by switching to laptop screen, then switching to external screen only, are they moved to the external monitor.


STEPS TO REPRODUCE
1.  Have both external and laptop screen enabled
2.  Have a window on laptop screen
3.  Switch to external screen only

OBSERVED RESULT
The windows on the laptop screen are not moved to the external monitor

EXPECTED RESULT
The windows on the laptop screen are moved to the external monitor
