Describe the issue

After upgrading to Mesa 24.1.4, I get corrupted AV1 video decoding when VAAPI is used at least in Firefox and MPV. The attached screenshot below demonstrates what the output looks like. After a quick review of the commits between 24.1.3 and 24.1.4, b0d6e58d looked suspicious, so I tried reverting it and that worked around the problem, returning the correct decoding.

Regression

It worked properly in 24.1.3 and below.
