On further checking I didn't get anywhere with this apparent "bug", which
shows when the water box is set amid the isosurface. Only thing needed to see
the defect (can't be certain it is though) is to have a pigment with filter or
transmit for the water. It's not caused by any other texturing such as
normals and finishes in either the water or island parts.
This pair of attached renders makes it very clear to see. The top is without
the water to show the unbroken isosurface. Bottom image has a filtered
pigment "water" and a normal and finish, but it still does this without like
I've said.

Whether the surface is at 0*y or above or below makes no difference.
