Colourful Glitches Radeon 570 OC, OpenCore, Apple Photos, Big Sur

[moosefuel]

Hi all,

I'm getting some really colourful graphics glitches on my machine while using Apple Photos. I've not encountered these when using Clover and Mojave, now that I'm on Big Sur and OC 0.6.5 they're actually quite annoying. You can see from the video here: https://vimeo.com/moosefuel/review/504153807/86a460f974
that when I adjust anything, the display glitches-out. I'm not sure how to begin investigating what the problem is so any help is appreciated.

Specs are as follows:
OpenCore 0.6.5,
RX570 OC, 4GB
i7 6700k,
Big Sur 11.1,
Apple Photos
AsRock Fatality K6 motherboard
16GB Ram

In the photos attached there is one clean pic and two really glitched-out ones.

Thanks.
