Green screen #25

I have installed Big Sur and works fine and I feel more speed than Catalina. But when i play movies in Apple TV the screen turns on green . This issue had been fixit previously with Catalina. But now, with Big Sur this issue returns.

I think this is something I've broken and forgot to fix...

In your boot args can you add shikigva=80 ?

(If it's already there just change the value to 80)

I have change the value to 80 but doesn't works.

Looks like this is down to WhateverGreen's DRM patches not working under Big Sur. I will keep this open until a fix is available.

Finally, I ve return to my old and stable Catalina. I hope new EFI will works fine. My issues was green screen on Apple TV and the usb wireless won't work, only ethernet . With Catalina works fine. Regards.
