I've looked through the commits and I can't see anything that would
obviously cause an issue. I've done some limited testing and don't see
any issues (will try again more completely later).

Can you help narrow it down at all?

Any broad idea when it started? Any particular config that causes the
issue? Hardware decoder/software decoder? Audio setup?

Essentially - any pointers:)

Thanks and regards
