You might be seeing what PowerView does with polygons whose
outline is concave. (e.g.: a single polygon shaped like an "L").
It seems to fill in the space from one side of the concavity
to the other with an non-existent dark polygon/shape/whatever.
There's also a problem with single polygons that have a hole or
depression in them.
(Convex good. Concave bad.)
Then again, these could be limitations of OpenGL...
