If you get an image that looks like the one below this is a bug with your PCs video card driver. We have only seen this with Dell PCs so far but it could affect other PC types as well. Basically, it is not allowing 3D programs using the latest OpenGL to use the correct color bit depth.
The solution will be to update to the latest available video card driver from Dell. If you are already on the latest video card driver then try installing the previous version.
