screenshot_vp9_rendering_issue
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 [1] 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 bug was also submitted to the kernel [2], but it was suggested in [1] that
this might be a better place to report it.
