--- Comment #5 from Ed <[email protected]> --- Fedora 44 KDE Plasma 6.7.0 + NVIDIA RTX 5080 multi-monitor corruption after login System: - Fedora 44 KDE - Plasma/KWin/KScreen 6.7.0-1.fc44 - NVIDIA RTX 5080 - NVIDIA driver 595.80 - Kernel tested: 7.0.12-201.fc44 and 7.0.11-200.fc44 - Three monitors: center 2560x1440, left/right 1920x1080 Problem: After transaction 224 upgraded Plasma/KWin/KScreen from 6.6.5 to 6.7.0, SDDM/login screen renders correctly across all three displays. After login, Plasma corrupts the desktop rendering. On X11 the center display renders incorrectly; on Wayland the failure changes location. Older kernel did not resolve it. Important log evidence: KWin crash log references: KWin::RenderLoop::activeWindowControlsVrrRefreshRate() Also seeing NVIDIA/EDID related warnings. What I tried: - Reboot - X11 and Wayland sessions - Older kernel 7.0.11 - Reset KScreen/Plasma monitor config - Re-applied xrandr layout - Confirmed NVIDIA driver loads - Confirmed monitor geometry is detected correctly - Windows drives all three monitors normally This looks like a regression in Plasma/KWin/KScreen 6.7.0 with NVIDIA/multi-monitor/VRR handling. -- You are receiving this mail because: You are watching all bug changes.
