Probably a good idea, now all data: geometry, normals and colors is fetched
directly from structure returned by surface method without any modifications.
I will play with vertex order as Tor suggested, but please take into account
that effect is mostly visible on high elevation (along the vertical axis).
Playing with surface parameters:
s = surf(x,y,z, FaceColor = 'interp', EdgeColor = 'interp');
gives nothing, also increasing mesh density eliminates this effect, as was

No doubt )
