Did you use radiosity for those images? If so, can you try again without
radiosity?
If it appears only when radiosity is enabled, chances are it will be
fixed with the next release.
Otherwise there might be some distance threshold hidden in the
superellipsoid intersection testing code; SSLT is quite sensitive to
such things, as it needs to shoot rays from just slightly below the
surface. I know that blobs have such issues, for instance. To really fix
that, I'd need to do some changes deep in the bowels of POV-Ray - which
of course is a no-go during release candidate phase.
