ebiten: on Windows 10 remote desktop not work.

I use Ebiten v1.9.3 and Golang 1.12 on Windows 10 Pro 1809. The following error occurred when trying to display the Ebiten window on the remote desktop PC.

panic: runtime error: invalid memory address or nil pointer dereference
[signal 0xc0000005 code=0x0 addr=0x0 pc=0x4f1262]

No. I understand you suggested Vulkan instead of DirectX, but as Ebiten’s graphics usage is very limited, I feel like using DirectX directly should be enough. Actually I’ve succeeded to port the graphics driver to Metal in Ebiten.

Again, as I said, I don’t plan to use Vulkan on Windows 😃

Or MoltenVK? I know there are such translating layers, but as Ebiten’s graphics usage is very limited, writing code that uses DirectX should not be so painful.
