[osg-users] Pass an osg::Texture2D to CUDA driver api

You need to disable display lists on your drawable. With display lists enabled it will only draw once and then use the display list. This makes no sense when using Cuda obviously.

I think this may also be related to the display list being enabled, the compileGLObjects() that is run in the first frame will compile display lists but not necessarily in the order of the render bins.

Cheers,
