Mica backdrop not working when RenderingMode is set to Win32RenderingMode.Wgl

[halfuwu]

Describe the bug

Title basically says it all, when using Win32RenderingMode.Wgl, the mica backdrop doesn't work. Was using mica in my program until I started integrating OpenTKAvalonia into my project and had to switch to Wgl rendering, then mica stopped working.

To Reproduce

Create a new project.
Set RenderingMode = [Win32RenderingMode.Wgl] in Win32PlatformOptions in AppBuilder.
Make a window with TransparencyLevelHint="Mica".

Expected behavior

Mica backdrop should be working? (Apologies if this is an already known limitation)

Avalonia version

11.1.0-beta2

OS

Windows

Additional context

AppBuilder:

That's expected, mica/acrylic require composition and directx based rendering (which is usually done via Angle OpenGL in Avalonia). It won't work with WGL.

Btw, WGL shouldn't be necessary for OpenTK with 11.1 avalonia. But it might require some adjustments.

thank you for the clarification!!

well I'll make sure to take a look then, not too familiar with the opengl binding with avalonia which is why im using that repo someone alr made

will do some research!!
