HD530 + AMD7000Controller.kext framebuffer issues

[theruck]

Hello,
hopefully someone will guide me to the right direction as i am once again desperate.
I have been using my Radeon R9 270X for years with 2 monitors but now i need to add a third monitor. The GPU is not capable to do so for whatever reason so i decided to enable the onboard HD 530 and try to go with iGPU+the Radeon GPU.
I had done the clover edits to allow the HD530 and installed LILU and WEG so i can boot the iGPU and work just fine.
The problem is when i plug in any connector on the Radeon card, the radeon framebuffer gets crazy.
One screen is garbled the other is always black.
If i boot the same setup without the iGPU, the Radeon card works perfectly as well.
I have tried with ATI inject, without ATI Inject,with ATI deinit and without, ATI patched connectors, without patched connectors, tried other Framebuffers (Hamachi, Futomaki) always with the same results.
The 3 displays are detected.

attached is the file with debug info + photo of the screens (the upper one is the iGPU working fine)
