[BUG] SKGLElement on multiple threads

Open imerzan opened this issue 1 month ago • 3 comments

Description

Using the new SKGLElement in SkiaSharp, I get an access violation at the following location in GLWPFControl when I try create an additional SKGLElement on a new Thread:

	public unsafe static IntPtr DXRegisterObjectNV(IntPtr hDevice, IntPtr dxObject, uint name, uint type, WGL_NV_DX_interop access)
	{
		return ((delegate* unmanaged[Stdcall]<IntPtr, IntPtr, uint, uint, WGL_NV_DX_interop, IntPtr>)EntryPoints[21])(hDevice, dxObject, name, type, access);
	}

Code

                var t = new Thread(() =>
                {
                    var form = new MainWindow(); // Main Window has an SKGLElement defined in XAML
                    form.Show();
                    // Start the Dispatcher loop
                    System.Windows.Threading.Dispatcher.Run();
                });
                t.SetApartmentState(ApartmentState.STA);
                t.Start();

Expected Behavior

Ability to create multiple controls (across multiple threads) in application like in SkiaSharp.Views.WindowsForms

Actual Behavior

Unable to do this
