Bug ID: 431546 Summary: Stutter on Wayland session Product: kwin Version: git master Platform: Other OS: Other Status: REPORTED Severity: normal Priority: NOR Component: compositing Assignee: kwin-bugs-n...@kde.org Reporter: david.alejandro.ru...@gmail.com Target Milestone: --- Created attachment 134805 --> https://bugs.kde.org/attachment.cgi?id=134805&action=edit The usual qdbus org.kde.KWin /KWin supportInformation SUMMARY Animations both on X11 and Wayland stutter, no matter the animation smoothness setting. Setting the "force smoothest animation" setting has no effect on making this any better. On Wayland, *everything* stops. Mouse movement, typing, everything. Nothing seems to be excluded from stuttering every 10 seconds or so for about half a second up to 2 seconds. Specially noticeable on mouse movement. On X11 it's not as extreme. It does stutter, but it doesn't pause *everything* when it does so, so I can see what I'm typing, I can move my mouse, etc. On Wayland the compositor just freezes everything every 10 or 15 seconds for like half a second or so. It's extremely bad. Video of the issue: https://youtu.be/5L_kVV2JGPU STEPS TO REPRODUCE 1. Install latest KWin master 2. Start wayland session OBSERVED RESULT 3. Everything stutters a lot. This seems to be hit-and-miss. On my laptop it's *fine*. On my PC it's horribly bad. And my PC is definitely more powerful than my lappy :p I got a video of it: https://youtu.be/5L_kVV2JGPU EXPECTED RESULT At the very least not this amount of stutter, but no stutter would be nice. Mouse movement not stopping. Being able to type a sentence without the compositor stuttering mid-sentence and not rendering what I'm typing until the (1 second or 2 second long) stutter stops SOFTWARE/OS VERSIONS Linux: 5.10.6 KDE Plasma Version: 5.20.80 KDE Frameworks Version: 5.19 Qt Version: 5.15.2 ADDITIONAL INFORMATION This is unrelated to 431509 and 431449.
