good find. wouldn't of even thought about looking at the way the channel was rendering.
i took a look at playback profiles last night so see if that could help, but there doesn't appear to be a way to change profile based on channel or something useful specifically to target this issue. My primary FE is a 3-4yr old celeron so doesn't do too well with some HD content so would prefer to keep vaapi enabled if at all possible.

What would be the proper long term fix - is this a bug or a config issue?
