strace of kwin_x11
It looks like i am also affected by this issue. I have two systems, which are
almost identical in terms of software (both openSUSE Tumbleweed on one of the
latest snapshots) and settings, but one of them is affected by this bug, and
the other one is not. The unaffected system has NVIDIA GTX660 GPU, and the
affected one has Intel HD Graphics 630.
Also, my experience is a bit different. For me, it is actually kwin_x11, what
produces the most CPU usage. However, even if i set desktop background to solid
black color, KWin still starts to use a lot of CPU after several hours.
Restarting KWin brings CPU usage to normal for several more hours. Setting
wallpaper to slideshow just causes the CPU usage to rise immediately (and
requires setting wallpaper back to solid color and restarting Plasma to return
CPU usage to normal). When KWin's CPU usage rises, strace'ing kwin_x11 shows a
lot of lines with DRM_IOCTL_I915_GEM_... (see attachment).
So, maybe this bug is less Plasma-related and more KWin-related?.. Or am i just
affected by a different bug? Anyway, if a can help by e.g. collecting some logs
on both affected and unaffected system, let me know.
