The problem might not look as obvious but would still exist.  If it is, as Ken
said, a problem with root solving, changing the texture won't fix the problem.

I'd do what Ken suggested -- moving the control points over by a very tiny
amount, small enough not to be noticable but large enough to make a difference
in the calculation (which shouldn't take much).
