The case that this does not cover is if a window is spread across several screens. In this case (only) then the size / placement ratio should be worked out taken the full width / height of all screens the window is spread across. Then in plug / unplug events those ratio can be applied just fine to the new screen config. -- You are receiving this mail because: You are watching all bug changes.
