--- Comment #10 from dominik.klementow...@protonmail.com --- What I noticed, is that my stack trace is different from OPs. Mine clearly points to this: https://invent.kde.org/plasma/kwin/-/blob/master/src/backends/drm/drm_commit_thread.cpp?ref_type=heads#L45 Looks like it never gets out of that `while (true)` and waiting for something that doesn't seem to be happening. Maybe it's because of some Ubuntu-specific patches to the kernel/drm library, but I don't know where to dig. Interestingly, OP attached this piece of log: >Sep 08 09:37:52 vesho kwin_wayland[3533]: kwin_wayland_drm: Pageflip timed >out! This is a kernel bug The error message comes from just 5 lines below of what my stack trace is pointing to (I checked and it only occurs once in the entire kwin source code), so looks like this is where the looping happens in both of our cases. -- You are receiving this mail because: You are watching all bug changes.
