VP9 Hardware Decode works but looks bad

[SHU-red]

Hi there,
im absolutely no expert in these things but i got my system running with

• Arch / Manjaro Linux
• NVIDIA 1060 6GB graphics card
• libva-vdpau-driver-vp9-git r57.509d3b2-4
• Chromium browser 96 and currently 97 started using several flags

Im playing Stadia gaming and with stadia enhanced chromium extension i can see VP9 decoding works
But as it works i get very bad artifacts for areas where the textures are moving slowly

Here an example

Can this be related to this repository?
Can i provide further information?
Is there another place where i can take a look?

Thanks

Honestly speaking, I don't know. If you have logs, they might be useful. But I think this is a bug in Chromium, actually.
Usually a refresh fixes this though.
