Bug 418548

SUMMARY

Having a multi screen setup, with two screens on a docking station, attached to a laptop. I have the laptop lid closed most of the time. However, every now and then, I need to open the lid (e.g. for a video conferencing session).

What happens is that the windows move to different screens. It looks like that the new screen is inserted before all other screens, all windows move one screen left. Closing the lid reverts to the original order.

STEPS TO REPRODUCE
1. Have two active screens and some windows open.
2. Open laptop lid, new screen gets added
3. Bang

OBSERVED RESULT

It looks like windows consistently one screen to the left.

EXPECTED RESULT

I would expect the application windows to stay on their current screen. No matter if a new screen gets added/removed. This is the behavior on GNOME and Cinnamon.
