Description Ana Clara Forcelli 2021-03-13 01:46:15 UTC

SUMMARY
Windows move to main monitor screen on unlock when the monitors are turned on at different times. The screens I use are of different models, so one takes longer to wake from suspension than the other.


STEPS TO REPRODUCE
1. enable a second monitor
2. put any window in there
3. lock the screen (Default shortcut is Meta+L)
4. turn off both monitors and turn them on at different times
5. type the password before the other monitor wakes (maybe timing is necessary)
6. it happens

OBSERVED RESULT
all windows will move to one screen without being solicited

EXPECTED RESULT
windows on a desktop stay on the same position unless the user tells them to move (or deletes the virtual desktop)
