Flickering on renders from M2 Mac

Our color grader reported multiple flickering Prores444 clips, all of them rendered with an M2 Mac. We did a bunch of re-rendering with an Intel Mac and they came out nice an clean. After a few tests I can confirm that the M2 renders are unusable. The flicker is small but very noticable in the scopes and can been seen with pure eye on high contrast shots.

Here's a screen recording to see the issue: https://youtu.be/-eMXjwSmOmw

The flickering has been seen on renders coming from two different systems (M2 Max Macbook Pro and M2 Ultra Mac Studio). I haven't had time to do much trouble shooting, but disabling hardware acceleration didn't help. I also noticed that the flicker doesn't happen on the same frames every time if I render the same clip twice.
