--- Comment #3 from Nate Graham <n...@kde.org> --- On X11, KWin can either do compositing, or not. When compositing is turned off, the system exhibits the symptoms that you're reporting. Can you go to System Settings > Display and Monitor > Compositor and see if "Enable compositor on startup" is checked? -- You are receiving this mail because: You are watching all bug changes.
