> Does this happen with -vo vdpau as well? No. It didn't happen with mapping video mixer output surfaces in GL either. This issue came up because mpv started to map video surface textures directly. > If not it sounds like the deinterlacing shader in mpv doesn't work 100% correctly. Any clue what could be wrong? (See linked mpv bug report.) Also, another user replied and claimed it got fixed by updating to Mesa 12.
