--- Comment #6 from haagch.christ...@googlemail.com ---
Just got a new monitor (again 1920x1080@60Hz) and booted with a fresh
mesa/xf86-video-amdgpu git + agd5f/drm-next-4.15-dc stack after not trying for
a while and I'm happy to say that I can not reproduce it. With kwin compositing
enabled, glxgears in fullscreen runs very smooth now.
One thought comes to mind looking at xrandr:
1920x1080 60.00*+ 50.00 59.94
Maybe there were some timing issues when the exact refresh rate wasn't 60Hz?
I tried with
xrandr --output DisplayPort-0 --mode 1920x1080 --rate 59.94
but glxgears is still smooth, but maybe that's not the case for all "slightly
off" refresh rates?
It bugs me that compton did not have this issue with the same ext_buffer_age
synchronisation method, so it must be something kwin did/does...
