Original Question:
Hello, I have a running hackintosh under macOS Big Sur with open core 0.6.4. Almost everything is working fine, but I have a small problem when using the ultrastudio mini monitor to get a clean video feed to my reference monitor with resolve for colorgrading. After a fresh boot green artifacts are appearing on the reference monitor screen. To solve this I have to unplug and replug the mini monitor while the computer is still on and then restart the computer. After that it works fine, but everytime I shut down my computer (without using restart), when booting up again it doesn't work again. And so on.
Does anyone have an idea how to solve this issue ?
