Xorg, OpenGL/Mesa and FreeBSD.

I have some Mesa/OpenGL code that I want to run on FreeBSD and Xorg.
The code compiles fine but once it runs, the window does not redraw --
hence it keeps a screen shot of whatever was behind it or whatever
moves over it. 

Any idea what could be wrong?  Some system info follows:
