Outdoors scenario with garbled graphics.

The Descent 3 game runs either awfully slow: using Direct3D as graphics driver,
or shows garbled graphics: using the openGL driver.

I'm running Descent 3 US 1.4.

See screen shot for an example of garbled graphics. The order of elements,
i.e., whats behind what, is broken.
