There is a bug in raytracing when clipping and capping surfaces. It
also occurs when clipping multiple surfaces without capping (e.g. two
contour levels of a volume). I've entered it in the Chimera bug
database, but 5309.
There's no way to work around it short of hand-editing the povray input
file Chimera produces. A viable alternative to raytracing is to use
silhouette edges (Tools / Viewing Controls / Effects) to put black edges
around surfaces with a light color background. I use edge width 2 or 3
and supersampled image saving (3x3) and generally prefer the appearance
to (working) raytracing.
