Seeing what you currently inject for iGPU properties, did you try the settings recommended in the Whatevergreen User Manual instead? Probably a good starting point as an alternative to this which clearly is incorrect:

And experiment with other framebuffers such as 0x3EA50009 to begin with.

You should also remove these kexts found in the original pack you got from Github:

  • IOGraphicsFamily -> can't imagine what this would do; a patched version used to be required many years ago to fix the garbled Apple logo at boot time but it's long been deprecated
  • CPUFriend + CPUFriendDataProvider -> the data kext would be specific to the OP's i5-8265U and should therefore be re-generated for your own CPU.

Then, of course, update all other kexts to latest version.
