Re: Opengl Shader Compiler issues with newer than 13.9 drivers on HD 5850

This line looks wrong:

  float vignette = vec2(1.0) - length(vec2(0.5) - vTexcoord) / length(vec2(0.5));

You're assigning a vec2 to a float. Change it to:

  float vignette = 1.0 - length(vec2(0.5) - vTexcoord) / length(vec2(0.5));

Thanks,
