Radeon HD 6850 Sierra disiplay issue

[Melvinzill]

Ever since installing Sierra on my Hackintosh I am having issues. The colours are constantly inverting (see pictures). I am using the Duckweed Framebuffer. I have also attached the config.plist. I didn't have these issues with El Capitan. Here are the specs of my hackintosh:
Gigabyte H81M-DS2V
Intel Core i3 4130
8GB HyperX Fury DDR3 RAM
Gigabyte Radeon HD 6850
Samsung 850 Evo 500GB
TP-Link N900 Wifi Card

I Hope someone can help

I have issue with sapphire nitro R9 380.

But I can see on your picture that you can boot right without black screen.
May be try another frame buffer or display color adjust.

I have tried the Duckweed Framebuffer (see picture). How can you do the display colour adjust?

Unfortunately this didn't fix my issue. Anything else I can try

Don't inject ATI and no need for Patch VBios (especially with no patch provided).

I have removed the inject ATI and Patch VBios. But it still doesn't work

I cannot diagnose "still doesn't work".
