Well, I have over 25 years of experience with display hardware and
what you describe here was never an issue.
I want to give you an example to let you know more.
I have a ASRock AD2550B-ITX board[1],
When another discrete video card is mounted into it mini PCIe slot or
PCI slot,
The IGD cannot be the primary display adapter anymore. The display is
totally black.
I have try to draft a few trivial patch to help fix this[2].
And I want to use the IGD as primary, does this count as an issue?
No, this is completely expected behavior and a limitation of the
hardware design.
As far as I know both AMD and Intel GPUs work the same here.

Christian.
