You can adjust the dotted-ness of the edges: see the "lines closer"
entry in the Cameras panel.  3-D graphics using Z-buffering, as the Irises do,
has a hard time dealing with objects lying at the same depth, like the edges
of a polygon.  The "lines closer" control displaces edges toward the eye.
How much closer they need to be -- without having edges be visible which
should actually have been hidden -- you'll have to find by experiment,
but probably a number in the range 10-100 will do.
