Can't repro on Linux, so going to tag this as Windows specific.

rmnvdns, can you attach about:support to the bug?

And can you also take Firefox Profiler with media setting during taking the snapshot like in instruction?

Bug 1911237 seemed to address the problem. It was uplifted to 129.0.2.

Confirmed that taking snapshot of the video uses canvas2d video rendering. Bug 1911237 should address the problem.
