    Having a Microsoft-mandated API (DXVA) to follow might be one reason. Another might be that hardware vendors actually test under Windows.

      What makes you think it doesn't? Chocking on some files happens because of the inflexibility of fixed function hardware compared to software that can be tweaked to handle edge cases, the OS doesn't matter. And wrong colorspace conversion happens in Windows too, depending on player and/or driver settings. But unless we're talking HDR, using the wrong conversion matrix will still produce fully watchable video, so you may not even notice that the colors are off.

        But it does or at least did. Specifically dxva2 had this problem which resulted in inaccurate colors. I tested this myself years ago with an HD 4650 card on Win7. Also you couldn't do separate chroma upscaling using dxva2. D3d11va did not have these problems.

          Does hardware AV1 decode work for anyone on tigerlake? So far I have tried it and in MPV it produce garbage on screen, with VLC it crash the system for me.
          Here is the bug in intel-media-driver that I've found but it is not resolved yet.
