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
