Hello,
there is presumably bug in AMD graphics drivers, which leads to massive stuttering while watching Youtube 1080p60 videos (vp9 codec).
During stutters I can see in HWINFO64 that the "GPU VCN Clock" goes from variable numbers to fixed 29MHz and sits there for long time. Also, Windows Task Manager shows "Video Codec 0" shows 100% usage. There is no other CPU or GPU load, no thermal throttling occuring. Windows 10 21H2, I've tried driver version Adrenalin 22.1.2 and Adrenalin 21.10.2 - there were no difference with the problem.
Also, I've sent reports about the problem using AMD bug report tool.
Any suggestions to resolve the issue? Thanks
