It doesn't process drm events itself though, the main thread is responsible for doing that. So when the main thread hangs, the commit thread also prints this warning in Plasma 6.2 (which will be fixed in 6.3, where it'll properly detect hang vs pageflip timeout). -- You are receiving this mail because: You are watching all bug changes.
