--- Comment #1 from Martin Gräßlin <mgraess...@kde.org> --- As a first step you can provide the output of: qdbus org.kde.KWin /KWin supportInformation when the problem is visible. As windows stop to update best do that from a tty. You can also try to press Alt+Shift+F12 twice when you see the problem. That should have the same effect as switching the backend. -- You are receiving this mail because: You are watching all bug changes.
