I am working with JOGL (latest stable version) on a 15" Macbook Pro running 10.6.8. My problem is that when I start any of my applications that make use of JOGL, it takes nearly 20 seconds for the application to start. For a good portion of that my display is completely frozen -- the cursor moves, but nothing else does. I initially wrote this off as some quirk of JOGL... until I watched someone run the same code on a 13" Macbook Pro and it started instantly.

After digging into this a little more I realized that the big difference between the two machines (other than the screen size and resolution) was that the 15" has two graphics options, integrated and discrete, while the 13" just has the integrated graphics option. When I force my machine to use the integrated card, apps start instantly. If I force it in the other direction to use discrete, I get the long startup times again. Not only is it strange that there is a difference, it is really bizarre that it works in the opposite direction than I would have expected.

Has anyone seen this before or know a fix (other than forcing the use of the integrated graphics option)? Should I file this as a bug?
