Product: kwin
Version: 5.24.3

Status: REPORTED
Severity: normal

STEPS TO REPRODUCE
1. Run "chromium --ozone-platform=wayland" with high refresh rate monitor.
OBSERVED RESULT
FPS are going down when using Chromium with higher refresh rate. Even with like
75 hz scrolling is not smooth. I tried to set my monitor to different refresh
rate and this what I measured. It's really weird.
FPS were measured from testufo.com
Chromium with
60 hz = 60 fps.
75 hz = 75 fps
100 hz = 100 fps
120 hz = 58 fps
144 hz = 58 fps
I tested Chromium on GNOME and Sway and I have no issues at all. It was running
smoothly. I have this problem only on KDE. I personally don't use Chromium
browser but this affects all programs that are running on Chromium.
EXPECTED RESULT
Run Chromium smoothly on Wayland with higher refresh rate.
