So, I have a very very strange problem. In MacOS, usually with the London Thames wallpaper enabled, I get banding, flickering, and ghosting after a short period of just the desktop being shown. The Mac is hooked up to three external displays and the one misbehaving is an MSI MAG251RX. It will carry over into Windows if I boot it up. It will sometimes disappear of I drop a window onto that screen.

I cant seem to force it and I'm stuck as to what could be causing it. I've also tried to see if I can reproduce it in Windows but so far no luck.
