avalonia-silk.net-example's Issues

Issue with Avalonia controls on top of Silk.Net - GL render missing

I made an app using code from example (without changes in GL part).
But when added buttons in the same area where located GL render, only buttons are visible, GL not displaying.
Is it possible to have Avalonia UI controls on top of GL? What should I change in example code, so both will work together?

Render YUVJ420P is abnormal

I use Silk.Net and Avalonia.OpenGL to play the rtsp stream, and add three textures for rendering, but the problem is here, avalonia will occasionally appear the following error:

Avalonia.OpenGL.OpenGlException: Unable to make the context current

My rendering code is as follows:

protected override unsafe void OnOpenGlRender(GlInterface gl, int fb)
 {
        this._gl.Viewport(0, 0, (uint)Bounds.Width, (uint)Bounds.Height);
         //Get YUVJ420P Frame
        if (this._playerBase != null && this._playerBase.OutputFrameCache(this._uniqueKey, out var frame))
        {
            this._texture.Bind(frame, this._shader);
            this._shader.Use();
            this._vao.Bind();
            this._gl.DrawElements(PrimitiveType.Triangles, (uint)_indices.Length, DrawElementsType.UnsignedInt, null);
        }
       Dispatcher.UIThread.InvokeAsync(InvalidateVisual);
    }

Can you tell me what caused this error, thank you very much!!
