Im using an Mac (Retina 5K, 27-inch, 2019)
3.6 GHz 8-Core Intel Core i9
128 GB 2667 MHz DDR4
Radeon Pro Vega 48 8 GB
Big Sur
And I'm not rendering anything - this is just normal playback. And the computer was running cool. And it's also weird that both glitches have dissapeared now, even though I was able to render out one of them (so not just a preview issue)
Very odd. Im scared to shoot in RAW after this
