Displacement map Issues

[Overdrive_Studios]

Hey guys, I'm sorry if the answer is obvious but I've tried everything (I guess) and I can´t seem to find a solution.

I've got a mix material with 2 specular ones to scatter light differently with each other with SSS (I've set the kernel to DL with 0 samples on everything to view it faster, even on PT the problem is still present).

The big issue in the border is what i've ran into. It only appears if I connect the displace node, otherwise, it's not seen and the material works correctly.
I guess my UV's are correct, what you can see is the tiling of the texture to illustrate my point.

I also tried changing builds, changing the ray epsilon, kernels, mapping on the texture tag and the nodes

Thanks in advance! I'm kinda stuck here

Hi Overdrive_Studios,
could you post a screenshot with the gray polygons selected in the Texture view?
Are you sure that those polygon are not overlapping or inverted in UVs?
What happen if you decrease the subdivisions of the Nurbs object?
