Bug ID: 381444 Summary: Stuttering when compositing is on Product: kwin Version: 5.10.2 Platform: Other OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: compositing Assignee: kwin-bugs-n...@kde.org Reporter: haagch.christ...@googlemail.com Target Milestone: --- This may be similar to bug 353038 but that one is old and I noticed it only recently. Whether it has been happening longer and I just didn't notice, I don't know. RX 480, latest mesa git, and I tried Linux 4.11-zen and 4.12-rc. Reproduction is simple: Start glxgears, use kwin to put it in fullscreen, observe it closely for a minute or so. You should see several small stutters in that time. If you let it run some time, it randomly starts stuttering more visibly for 2-3 seconds and then goes back to normal. If you don't see it, try adding the gallium fps graph and let it update every frame: GALLIUM_HUD='.h1000.w1000.c70fps' GALLIUM_HUD_PERIOD=0 glxgears Watching the fps line closely should make the stutters more visible. I do not believe it's the fault of the drivers because with compton this does not happen. I tried kwin 5.10.2 and latest git, it happens on both. I only really tried on Xorg. -- You are receiving this mail because: You are watching all bug changes.
