Lighting Issues on Mac OSX Lion, Intel HD 3000 Graphics Card

When I updated my MacBook Pro to Lion, suddenly I started seeing several "black polygons" showing up in the TGE game I worked on several years ago, TubeTwist. I have also seen the same issue in ShowTool, another old TGE product, so I know this is not specific to TubeTwist. The black polygons show up at certain angles, so this is most likely a lighting issue.

My MacBook Pro has an Intel HD 3000 Graphics Card. I have another Mac that has an ATI card, which I also upgraded to Lion, and it does not show the same issue. So apparently this is a driver issue, as it only happens on the Intel HD card, and only after upgrading to Lion. I had hoped that Apple would fix the issue in a Lion update, but so far they have not.

I wonder if anyone else has seen this issue and has found a possible workround?

Here is a video showing the problem: www.youtube.com/watch?v=bsTC3rY39fg&feature=youtu.be

You can see how the triangles quickly shift from colored to black. I'll make another video on the computer that doesn't have this problem.

Here is the same model on my older MacBook Pro, which has an ATI graphics card. No issues.
