            Bug ID: 381471
           Summary: High GPU load causing heat and battery drain
           Product: kwin
           Version: 5.10.2
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: compositing
          Assignee: kwin-bugs-n...@kde.org
          Reporter: gr...@sub.red
  Target Milestone: ---

I'm really not sure with this one, because I don't know how to investigate
here.

For a while I've been observing constantly high GPU load even while doing
nothing. This causes the battery to drain, wasted energy and heat. I can
confirm the GPU is under load in intel_gpu_top and radeontop (on another
computer). Also, I've installed GNOME to see if it might be a driver problem
but I don't have high GPU usage with that DE.

Is there some tool where I can show which process is actually causing GPU load
or what's happening on the GPU?
