Heavy color compression artifacts on Surface Pro X (issue 9-0583000030587)

Hi, I'm playing on a Surface Pro X (Chrome) and I'm seeing some heavy colored artifacts in the video stream and they get worse as you play.

Found out that disabling hardware decoding in Chrome (#disable-accelerated-video-decode ) solves the issue but kills battery life.

Any other VP9 video (e.g. youtube VP9 samples) are decoded in hardware without problems.

Also chrome://gpu/ says VP9 is supported:

Decode vp9 profile0	16x16 to 8192x8192 pixels
Decode vp9 profile0	16x16 to 8192x8192 pixels
Decode vp9 profile2	16x16 to 8192x8192 pixels
Decode vp9 profile2	16x16 to 8192x8192 pixels

Would be great to know if Google is aware of the issue and/or is working on a fix.

Thanks

have the exact issue, puts me off playing it, if I turn off hardware acceleration it fixes it but at a performance cost

Hi, you can also try to force H264 using Stadia+ 3rd party extension (https://github.com/Mafrans/StadiaPlus ) and this will fix the problem.

Still, it's a 3rd party extension, it's not guaranteed that you'll be able to force H264 in the future and VP9 is supposed to have better compression so, depending on your connectivity, you could be short on bandwidth.

It's really a pity that Stadia couldn't at least repro and acknowledge the issue.

I'm having a similar experience on my TV. It only appears after a few hours (2-3) and for me these artifacts are only visible, when playing on my TV (Full HD) using the Chromecast Ultra. And they are only in some parts of the image and not everywhere.

The first time I saw these artifacts was roughly December 2019. So it's not a new problem for me.

Does somebody know if Google is working on that?
