showZBuffer quits Rhino when Antialiasing is enabled

This happens instantaneously when antialiasing is set to anything else than zero and perspective view is maximised. I also tried version 5 to compare, with the same results.

It partially works with antialiasing set to 2 or 4 when all 4 views are active and the resulting view is of course smaller then. But the result shows a warped outcome. The image below is supposed to be a regular cube.
