I've also started having an issue with colors not reproducing properly on my 2nd monitor after installing 20.12.1 yesterday. Everything was looking fine before the install, but now all yellows look pink, all blues look green and all greens look blue. I tested the monitor on a different computer, using a different GPU and it works normal, also the DVI cable tested and working fine. Not too sure what to do here aside from trying to roll back drivers, but that is a mess I am not looking forward to cleaning up if it doesn't work.
The yellow background for the Cyberpunk 2077 Discord should not be pink...
