Richard Kampmann <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #10 from Richard Kampmann <[email protected]> --- I can reproduce the same type of issue on a different platform/setup. My system: - openSUSE Tumbleweed - KDE Plasma 6.7.3 - KWin 6.7.3 - KScreen: 6.7.3 - X11 session - Intel UHD Graphics 620 - Mesa 26.1.5 - OpenGL/GLX compositor -OpenGL vendor: Intel - OpenGL renderer: Mesa Intel(R) UHD Graphics 620 (KBL GT2) - OpenGL version: 4.6 (Compatibility Profile) Mesa 26.1.5 - GPU: Intel UHD Graphics 620 (Kaby Lake-R) - Kernel driver: i915 - Xorg driver: modesetting Hardware: - Dell Latitude 7490 - Dell Thunderbolt Dock TB16 Displays: - 3840x2160 @60 Hz (DisplayPort) - 3840x2160 @30 Hz (HDMI) - internal 1920x1080 @60 Hz Monitor layout: DP-1-2: 3840x2160 @60 Hz, position 0,0 DP-2-1: 3840x2160 @30 Hz, position 3840,0 eDP-1: 1920x1080 @60 Hz, position 7680,1080 Virtual screen: 9600x2160 The symptom is the same: A one-pixel-wide strip of window content appears on the adjacent monitor when a window touches a monitor boundary. Additional observations: - It is not limited to maximized windows. - Manually resized windows reproduce it when their edge touches a monitor boundary. - xwininfo reports correct window geometry. - The issue disappears immediately when KWin compositing is disabled (Alt+Shift+F12). - Disabling window shadows does not change the behavior. - Restarting kwin_x11 --replace does not reliably remove it. - The issue can occur in both directions depending on the window: one window may bleed to the right monitor, another one to the left monitor. This looks like the same underlying KWin rendering/clipping issue rather than a monitor geometry problem. This report appears to be related to the existing issue, but this is a separate reproduction on X11 with Intel graphics. -- You are receiving this mail because: You are watching all bug changes.
