I've encountered what appears to be a bug in the renderer.

By creating an Icosphere in blender and subdividing the surfaces, I've found that somewhere between 21,000 and 21,600 faces, the sphere fails to render properly. I don't know the proper term for the problem, but it seems that some vertices don't make it into the mesh, and so the triangles now render between the wrong vertices.

Here's an [image](http://i.imgur.com/WFXv5.png) of the problem.

Likewise if I create a sphere in code, I get a similar result: [image](http://i.imgur.com/1LGW6.png).

I'm a 3D noob, so let me know if I'm missing something.

Thanks!
