D3D11 rendering doesn't work in Skia #16411

Open amerkoleci opened 4 months ago

amerkoleci commented 4 months ago

Describe the bug

https://github.com/AvaloniaUI/Avalonia/blob/master/samples/GpuInterop/D3DDemo/D3D11DemoControl.cs doesn't work when using Avalonia with vulkan while it works with OpenGL Angle backend.

Probably vulkan Skia need to import the d3d shared handle.

I can submit PR if someone can guide me on the Skia vulkan backend.

To Reproduce

Uncomment this line https://github.com/AvaloniaUI/Avalonia/blob/master/samples/GpuInterop/MainWindow.axaml#L9 and comment the line bellow

Expected behavior

It should work as with OpenGL backend enabled

Avalonia version

11.1.0

OS

Windows

Additional context

No response

Vulkan backend currently only supports VK_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_BIT and VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_OPAQUE_FD_BIT.

For D3D interop to work other handle types need to be added.
