Hi bdfd.
I have the same problem sometimes. It happen to me when the project area is a bit too big or when the models are complicated for sh3D renderer. And your problem is in GEODESIC objects. I had the same. Glass GEODESIC objects are really complicated for rendering. And you use not only 1 but 10 in your project!!!!! Your graphic is going to be mad
.... Try to hide every objects you can't see in your focus during rendering.It helped me.
Or try to use lower AA setting if you use 1.3.1. renderer
