The normal node itself will not cause this - but it looks like whatever noise nodes you are using are responsible for the "stretching." Cannot determine the source without looking at more elements of the graph.

so logically this happens because it's a one channel displacement. it can only displace up or down, there is no sideways information. That's why in VFX when this kind of case becomes an issue, vector displacement can be used.

update fro yesterdfay ......i got this reply on unreal egine forum in face book its common issue ,,, some mentioned increasing the tessalation .... but this doesnt seem to b eavialble in substance when choosing parralx occlusion ..... some mentioned just by blurirring the edges of the hexagon at the beggining of the normap map and height map creation will remove harsh edge .....it does fix the issue some height is lost
think it be good enough to use and sell
