Confirming this is an issue in 5.23.4, on X11, with kernel 5.15.12-1-MANJARO
(amd64), amdgpu, mesa 21.3.2.
I've checked, and I do have `MaxFPS=144` under `[Compositing]` in kwinrc.
Still, compositing on my 144 Hz monitor is limited to 60 fps. If I disable
compositing, then moving windows, scrolling websites in Firefox etc. is smooth
again.
I used to be able to work around this by setting the compositing backend to
XRender. In 5.23, XRender has been removed, so I'm stuck again.
My setup is:
* 1920x1080 60Hz @ 0,840
* 2560x1440 144Hz @ 1920,400 primary
* 1920x1080 60Hz @ 4480,0 rotated left
Observation: There is no screen at 0,0 in my setup. In bug #438176, Oto Šťáva
mentioned that that has an effect on whether they experience compositing
issues.
I've tried changing every compositor setting in the kcm, to no avail. The only
thing I haven't used is "keep window thumbnails: always".
