--- Comment #8 from H4nN1baL reizemberk@gmail.com --- I have this same problem but in r600g since 2017-05-17, my report in mpv: https://github.com/mpv-player/mpv/issues/4433
In my case, the issue only manifest using: 'mpv --vo=opengl --hwdec=vdpau'
I think this other issue is also related: https://github.com/mpv-player/mpv/issues/4430
