--- Comment #4 from Kai Uwe Broulik <k...@privat.broulik.de> --- I'm pretty sure that's it. What happens: It iterates all screens and compares them with each other to find an overlapping one. If one screen is disabled, depending on the order (i.e. whether it is checked in the outer or inner loop, the inner loop missing the check for output being enabled) it will still consider them mirrored. Disabled screens are also usually placed at 0,0 (as it doesnt matter) "overlapping" leading to the bug you're seeing. -- You are receiving this mail because: You are watching all bug changes.
