Same issue on HD 5870, with two displays connected thru DVI. The colors are not inverted, as I initially thought, blue gets changed to yellow, yellow to green, orange to blue, red to purple, but all the grey stuff like Finder windows are still grey. And the changes are irregular, sometimes a few seconds of either distorted or correct colors, other times flickering like crazy. I think it's related to refreshing the screen, when I drag a window around the frequency of the changes increases by a lot! Same story when watching a YouTube video. Moving the mouse around the screen does not affect the frequency.

I'm on Clover r4035 and most up-to-date FakeSMC (2017-01-17)

Enabling HD4000 on my 3770K results in normal operation, but only on the HD4000 connected display
