mpv 0.20 video screenshot

kernel: 4.7.5
mesa: 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 !

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

From what I can tell this problem was introduced in fb827c055cb1bdd2b18d0687c06c56b537d805f3 as a1e391e39df2b1d8169e773a30153167ab8e13e8 does not exhibit this problem.

Forgot to mention:
I'm using Radeon R9 R270 (PITCAIRN)
When playing video with that commit screen gets corrupted and video does not play smoothly.
