Public bug reported:
When playing a video file with frame rate that matches the refresh rate
of the monitor there is a stutter every couple of seconds (5-7)
50hz playing 50fps video
60hz playing 60fps video
24hz playing 24fps video (this one was tested on a nother system running arc
a310)
The lower the refresh rate is, the more obvious the stutter is.
Easiest way to see it is to play a tearing test video that has vertical
bars running across the screen.
Seems that at regular intervals a previous frame is shown, its like the
internal frequency calculation is off and corrects itself every couple
of seconds.
This happens with all players that I tried - Kodi, mpv, also happens in
chrome and firefox when playing a youtube video.
Tested it on 2 systems - this one is integrated intel graphics, second
system is newer - with a intel arc A310 video card - both systems does
exactly the same thing.
