This is caused by abutting polygons which happen to fall on a non device
coordinate boundary at render time.

Make a new PCB in PCB, stick a plane in it, and drop some vias to cut
into it. PCB dices this up into separate polygons, and it should trigger
the rendering glitch when you export the gerber file and view it.
