Thinkpad T480 Color banding

[bugraduz]

how can I fix this? Animations are also frozen. I guess the color bit depth is too low. I am using Catalina 10.15.

You need to use skylake ig-platform-id (0x00, 0x00, 0x16, 0x19) with spoofed device-id (0x16, 0x19, 0x00, 0x00). also you need to use boot-arg "lilucpu=8"
