Created attachment 126949 --> https://bugs.freedesktop.org/attachment.cgi?id=126949&action=edit mpv 0.20 video screenshot

kernel: 4.7.5 mesa: git llvm/clang: git

While playing videos I get kernel messages like this:

Oct 02 09:02:53 sun kernel: [drm:radeon_uvd_cs_parse [radeon]] *ERROR* Handle 0xa7c20001 already in use! Oct 02 09:02:53 sun kernel: [drm:radeon_cs_ioctl [radeon]] *ERROR* Invalid command stream !

and screen is corrupted (see attached file). mpv options are a follows:

vo=vdpau hwdec=vdpau
