I think it's version 10.11.2 of the Blackmagic driver on a macOS 10.12.6 here or Aja 15.0.1 on macOS 10.12.6.
Session is not too big. Stereo TV Mix on a HDX2 or HDnative system with ~ 150 voices used.
Native video, no drivers needed!!

Is it a native Desktop Video issue only then?

Having the same issue here since upgrading to 2019.10. Video loops small sections, usually if I work on a short section of audio for a bit, then start playback, the video will loop the short section I was working on. Bizarre. Video will also freeze on a single frame, while timeline continues playback.

Blackmagic Decklink Intensity Pro card, 11.3 drivers.
QuickTime Prores Proxy videos, and MXF's from Adobe Premiere CC 2020.

Hope they can fix this.
PT Ultimate 2019.10 // Mac Pro 2012 // High Sierra 10.13.6 // BlackMagic DeckLink Intensity Pro

I'm seeing this as well now,
not random loops though, it seems related to selection where I copy/pasted to or wrote automation to in preview mode. The loop is exactly a certain selection I made.

Bump - as this one is a show-stopper if you have clients, and disruptive enough to workflow even without people over your shoulder.

Of course I'm working in an earlier version when I have clients, but am curious:

1. if anyone has seen this officially addressed
2. if most people are NOT having this issue
3. if the current update .12 solves the problem (though it is not listed specifically in the bug fixes)

#2. I haven’t seen this issue since I posted over a month ago. Sierra, 2019.10, AJA T-Tap, ProRes proxy video. All good.

I experienced this looping bug for the first time today. Disabling and enabling the Video Engine once cleared it up. Still pretty disconcerting, though. Guess I'll give 2019.12 a try after all.

After installation, reset the prefs ans so on, 2019.10 seems to work on my system (high Sierra HDX). In editing process all was ok.

But after the session becomes complex, i began to have black screens after ten minutes, then after one or two minutes of playback.

Then the video begins to lag sometimes, stop or turns to black.

It was really unusable.
I switched back to 2019.5 and everything went smooth again.

I tried different codecs, DNX36 of course, but also Prores, or H264, but nothing really worked.
