See attachment on how a video encoded with VP9 format is being rendered with hardware acceleration enabled since I upgraded the kernel to 4.13.3. There is no issue with playing H264 videos. Downgrading kernel to 4.12.12 resolves the issue. A few people in https://aur.archlinux.org/packages/chromium-vaapi confirm the same behavior.


Reproducible on ArchLinux with mpv or chromium compiled with VA-API. 

People who confirm this bug have the following CPUs: Intel i7-7820HQ, i7-7500U, Pentium n3450.

This seems to have been fixed in [1]. See [2] for details. Thus closing.
