My best explanation is that this is a NVidia driver bug, there is no
reason the decoder should care about aspect changes.
In the worst case the decoder would only compare aspect-scaled sizes,
in which case it might be a security issue.
Can someone try this patch?
It might still avoid the original issue why possibly fixing this one.
Assuming the issue is with the decoder, and not the video surfaces,
the error message is a bit useless there.
