It should be filter, but the filter heuristics actually has trouble
distinguishing real videos from gnome desktop, resulting in bad display
quality.  Switching to "off" was meant to be a temporary stopgap for
that.

Anyone can comment what is the state here?  Became the heuristic better
meanwhile, so we can flip it back to filter?  Otherwise we should
probably fixup the docs to match reality ...

Hmm, can't reproduce.
What is the exact command line leading to this error?
