Cheers. The issue I'm thinking of is the self-shading problem with non-manifold objects in FSX. This results in black lines straight from the broken object to your vehicle cockpit. Basically, any object which has self-shading needs to be manifold, in that it can't have any 'holes'. I'm sure there are a still a few non-manifold objects around... This will really be very specific to an actual addon scenery, I suspect.
No easy fix, short of turning off shadows. Or get rid of FSX.
