            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.
