I have this with VP9 on an XPS 15 with `Mesa Intel(R) UHD Graphics (CML GT2)`.

As a wild guess, it looks like the GPU is consuming truncated encoded frames, so it might be there's some missing fencing/synchronization and the GPU tries to read the encoded frames before they're properly transferred, or missing cache invalidation.
