The larger the patch size, the larger the difference is likely to be.In your scene the issue is caused by the mask you are applying to the surface layer. The mask has some very high frequency (small scale) and high contrast components, and these are causing the surface to rapidly switch between the smoothed and non-smoothed surfaces. I don't think there's a bug here, just a particular combination of shaders producing an unwanted result.One way you might be able to resolve this is to reduce the roughness of the masking fractal.EDIT: The mask's "feature scale" is currently 5, and this will need to be much higher if you don't want spikes. It probably needs to be at least as large as the patch size.
