GPU - Intel UHD Graphics 630
GLWpfControl - 4.0.0 - 4.3.2
Can't create GLWpfControl, DXOpenDeviceNV returns an empty GLDeviceHandle, DXInterop.GetLastError shows -1073283022 and Marshal.GetLastWin32Error shows 0, so not sure why this is happening.
Previously I thought that this might be due to missing NV_DX_interop support, but Wgl.Arb.GetExtensionsString does show this string.
I've tried changing multisampling samples, opengl version from 3.0 to 4.6 and context profiles, but neither seems to have any impact.

So this is either integrated+dedicated gpu issue, or a multi-monitor issue. I've successfully created and rendered the example project (except with multisampling enabled) after specifying to only use the integrated card in bios and starting the pc with a single monitor. I'll test more when I get to pcs with only integrated gpus.
Both monitor cables in dGPU slots runs fine on dGPU but results in empty GLDeviceHandle when running on iGPU.
One monitor cable in dGPU other in iGPU slot runs fine on iGPU but throws WGL: The driver does not appear to support OpenGL trying to create NativeWindow when running on dGPU.
Interesting thing to note though, when rendering on iGPU, everything seems to render correctly but the debug callback is actually showing this error: [DebugSeverityHigh source=DebugSourceApi type=DebugTypeError id=1282] Error has been generated. GL error GL_INVALID_OPERATION in FramebufferRenderbuffer: (ID: 1914656587) Generic error
This happens at ReallocateFramebufferIfNeeded when trying to attach depth-stencil renderbuffer to framebuffer.
Hopefully in the next version we'll be able to fix a lot of the integrated graphics issues.
No guarantees though. Any info or updates are appreciated in fixing this issue.
