bug: terrain holes

Steps to reproduce the bug: Look at the terrain from various camera angles.

Observed results: I don't know what causes it but I've seen it twice at different times in Sandbox Island and thought I'd report it. Might be related to occlusion culling, but disabling it (or vertex shaders) has no effect so dunno.

Expected results: Terrain shouldn't have holes.

yes, same here..more than once..but this was in a particular area. hasn't happened to me since i left that area. Came back to see to if it would do it agan, and findings were good. no "holes" were see this time.
