--- Comment #10 from Martin Flöser <mgraess...@kde.org> --- We recently got several graphics issues and what they have in common is the newer Mesa version. If you are able to downgrade Mesa, that could be worth a try. Given the screenshot I doubt it's a problem in KWin, but rather lower in the stack. What's extremely showing is that xrender hasn't seen any functionality changes for quite some time, so a regression there is extremely unlikely. -- You are receiving this mail because: You are watching all bug changes.
