As I posted in the main 1.6 thread...the "my screen turns yellow near fire" issue cropped up in the beta with AMD cards running older driver versions. If you are seeing this issue and you have an AMD card and haven't updated your drivers in a while, the correct fix is
upgrade your drivers.Disabling in-game AA should only be done if you can't upgrade your drivers...for example if you have a laptop and the manufacturer provided drivers are quite old, and there haven't been any new ones issued lately. It's just a bandaid fix.
As for the flickering issue, I'm not certain about that one, and I can't get into the beta forums to double check if that one's been reported / if there's a fix, since of course the beta forums are closed. chart4ever, what's your GPU, are you using Crossfire, and what's your driver version?
