Try Mesa 6.5.2. Simply because of this problem, the first suggestion I received was to try the latest GIT version, so I did.

I had high hope for that once you mentioned it, since maybe 'processing' might be using some older functions to carry out the operations. I am not entirely sure about Simon's tutorial example I mentioned any more, there's some disk access slowing it down so maybe I am back to this, the way processing uses opengl? So maybe I need to learn to use opengl directly from a C program . </BODY> </HTML>
