[Help] Flickering Issue around transparent objects on iMac 12,2 with Big Sur

[Help] Flickering Issue around transparent objects on iMac 12,2 with <a class='btn-link text-primary' href='/2020/12/install-macos-big-sur-on-supported-pc.html'>Big Sur</a>

Hi everyone,

I've installed macOS Big Sur on my iMac 12,2 using OpenCore Legacy Patcher. Everything works fine except for some screen flickering around transparent objects (like windows or menus).

specs: CPU: Intel i7-2600 GPU: AMD Radeon 6970M 2GB

Has anyone experienced this issue before? Is there a specific setting I should tweak for the graphics card to fix this? Any help would be appreciated!

Thanks in advance!
