xBR Filter

I'm attempting to use the xBR upscaling filter in MonoGame. I have converted this StackExchange answer from XNA to Monogame.

This involved the following changes in the game:

// Original:
this.xbrEffect.Parameters["textureSize"]
.SetValue(new float[] { renderBounds.Width, renderBounds.Height });

// Changed to:
this.xbrEffect.Parameters["textureSize"]
.SetValue(new Vector2( renderBounds.Width, renderBounds.Height ));

And in the shader:

// Original:
VertexShader = compile vs_3_0 main_vertex();
PixelShader = compile ps_3_0 main_fragment();

// Changed to:
VertexShader = compile vs_4_0_level_9_3 main_vertex();
PixelShader = compile ps_4_0_level_9_3 main_fragment();

The result is a white screen with intermittent flickering of the expected image. The flickering image does not have the filter applied correctly. My knowledge of shaders is incredibly limited. I can only write very simple ones, with the help of examples. Where is this going wrong?

You can download the Visual Studio Solution from here, if it helps.
