title: YUV to RGB shader border artifact
body: <p>I have YUV to RGB conversion shader.</p>
  
  <pre><code>struct Pixel_INPUT
  {
      float4 pos  : SV_POSITION;
      float2 tex  : TEXCOORD0;
  };
  
  Texture2D textureY : register(t0);
  Texture2D textureU : register(t1);
  Texture2D textureV : register(t2);
  
  SamplerState samstate
  {
      MinFilter     = Anisotropic;
      MagFilter     = Anisotropic;
  AddressU = Clamp;
  AddressV = Clamp;
  };
  
  float4 PS(Pixel_INPUT input) : SV_Target
  {
      float y = (1.1643f * textureY.Sample(samstate,input.tex) - 0.0625f);
      float u = textureU.Sample(samstate,input.tex) - 0.5f;
      float v = textureV.Sample(samstate,input.tex) - 0.5f;
  
     float r = y + 1.5958f * v;
     float g = y - 0.39173f * u - 0.81290f * v;
     float b = y + 2.017f * u;
  
     return float4(r,g,b,1);
  }

  <p>But I have a green line at right side of image like that:

  <p>I use Clamp address mode and image is more yellow color than the original.</p>
