Bug in new video engine 2019.10

[Meads]

I've been putting the new engine through its paces the past couple days and noticed some weird behavior I hadn't seen with the old engine.
Sometimes when I hit stop and play the video plays back in a random loop while the playhead continues through the session normally.
I haven't yet been able to pinpoint a certain trigger for that, but it happens with newly build sessions in 2019.10 as well as with older sessions.
My video files are always ProRes 422 (Proxy), nothing in my setup changed except for the upgraded PT install. Same drives playback the same files in the same sessions.
Never had this issue before.

I also use ProRes proxy (with an AJA T-Tap) and saw this last night, but it was while I was toggling the Weiss plug-in pref for OpenGL graphics. As soon as I said yes to OpenGL and rebooted, all was good. Or maybe this was coincidence.

Video has been fine for me today.

Interesting. I'm using the Weiss-Deesser in most of my sessions.
Just checked the OpenGL setting and it has been ticked already, so I guess that's not it, as it just happened again.
It's not that big a deal since toggling the video offline/online always solves it for me. But should still be worth a fix.

I noticed an odd loop today with 2019.10. Playing the last minute of a 45 min show and expected to see the credit roll and got a loop of about 5 secs from video that had already been played. Pro Res proxy file type. 25 fps.

Haven't seen this here but all our picture is DNxHD36. And no Weiss plugins installed.

I just had it that instead of looping the video freeze framed.

Still haven't figured out, when it does it, but it happens several times a day.
I have a feeling it occurs when hitting play while PT is still busy with another task. I'm very quick when it comes to editing. For instance cutting the end of a clip, creating a fade out and hitting play basically is one action. A quick burst of key commands. Seems those playback issues always happen in one of those instances. But then again I could be totally wrong, it's just a hunch.

Will report back when I figure anything out.

Same here DNXHD36 mxf video.
Only when I upgraded to 2019.10

Does QuickTime DnxHD36? Mixing a smaller TV 90 Minute feature here and it's ok.

I can confirm that I am also experiencing this looping bug. I can get it to stop if I make a cut in the video track.

I have also been having odd issues with 2019.10 AVE.

I have gotten AVE errors without video in the session. Choppy playback.

The oddest one that I have had is when I would import video into a session and the video settings wouldn't change automatically to match the video format. Pro Tools used to do this. (ie, if I imported a 29.97 video into a 23 session, previously it would play the video back at 29.97 and let me know there was an issue. Now, it tries to play the video back at 23.98)
