(...) Just as a note, I found that Vertex Buffer Objects (VBOs) would crash my ATI card in Windows when used inside a display list. As far as I can tell, this isn't supposed to happen.

(...) Maybe you're running into one of those weird oddities of the Apple opengl drivers. For example rendering to the GL_FRONT buffer really renders to a hidden back buffer. There are times where this setup causes you to use triple buffering, which (...) (22 years ago, 17-May-04, to lugnet.cad.dev.mac)
