--- Comment #8 from rick...@refused.net --- It happens with any window when it's close enough to the bottom bar or is maximized. Kcalc, Kate, Konsole etc. Firefox just happend to be close enough to cause the issue, making me think it was Firefox that caused it. So to summarize: * Happens when any window is close enough to the bottom bar or is maximized, and the bar is set to adaptive opacity * It even happens if a window is maximized/or close to the bottom bar on the second desktop and you are on working on desktop 1. * Setting bar Opacity to translucent or opaque for the bar makes the issue go away. * It's not related to Vsync at all. Sorry for the confusion but it really made no sense, when sometimes everythiing was ok and suddenly it wasn't, then it was ok again. When it all really was how the windows were placed. -- You are receiving this mail because: You are watching all bug changes.
