If you set the > KWIN_DRM_PREFER_COLOR_DEPTH=24 env var, does that make the display work at > 4k60? No, unfortunately it does not help. I thought this would be the cause because the projector reported 10bpc / yuv444, but now it still fails. I tried to get debug information with drm.debug=0x1ff (see attachment), - but I can't tell from it what's going on and if it is a driver bug. It seems strange though that kwin again and again removes the frame buffer after the atomic mode set and then tries to add a new frame buffer? -- You are receiving this mail because: You are watching all bug changes.
