[Fix] Enable present extension for GPU screen so it can be a viable CRTC to be selected. [Test] On a I+A laptop and external displays are routed to AMDGPU, disable internal display like closing lid can observe the issue. With the fix applied, the external display becomes very smooth. [Where problems could occur] I personally don't see why GPU screen can't use present extension, but this is Xorg so there might be some arcane reasons I didn't think of.
