Yes, it's the case, at least as soon as the figure is in 3D. In 3D, 
every surface defined by a set of (not necessarily coplanar) vertices is 
decomposed as a set of joined triangles.

These "edges" are not extra drawn lines, but a very thin space (likely 
1-pixel thin) in-between almost joined triangles edges. Indeed, changing 
the background color changes their color.
The fix would be to output some triangles oversized by 1/10000 ?
This could have some potential drawbacks, like (partly) hiding some 
lines actually drawn as edges, etc.
To be assessed.
