--- Comment #3 from Alexandre Demers alexandre.f.demers@gmail.com --- With the patch, when playing problematic videos, I get a black screen instead of a partial display with green artifacts.
Also, with and without the patch, dmesg catches the following when playing the problematic videos (I should have had a look previously): [76261.125581] [drm:radeon_uvd_cs_parse [radeon]] *ERROR* Handle 0x8fd80001 already in use! [76261.125594] [drm:radeon_cs_ioctl [radeon]] *ERROR* Invalid command stream ! [76261.126059] [drm:radeon_uvd_cs_parse [radeon]] *ERROR* Handle 0x8fd80001 already in use!
