Well I played with this at work today. * You can drag/move windows when its "frozen", mouse updates as usual when draging occurs just it won't update the screen/window position other than the mouse. * When toggling compositing with with the combination the moment you turn compositing off the screen updates quickly as nothing has happend. The freeze will also only occur when compositing is enabled. Turning compositing off with the combination and then plugging in the external monitor just works. * I tried the 'KWIN_USE_BUFFER_AGE=0 kwin_x11 --replace &' but the corruption still occurs. -- You are receiving this mail because: You are watching all bug changes.
