We already know about this backtrace. It's a possible sideffect of a
overloaded/dying gpu, but unrelated to the bug at hand.

Not at the moment, unfortunately. Can you please report a bug against
libva with a small summary of all the things we've already discussed here?
Also please add a error_state with my patches applied. And don't forget to
put me on cc and post the bug # here in this thread.
Yours, Daniel
