In our Performer (Pf2.2) application (Onyx2 - 3 channel, 1 pipe) we have
problems with (I suppose) triangle clipping.

Depending on the viewpoint (large pitch angle) we often "loose" some
triangles. It's a flickering of triangles with very small changes in the
pitch angle.

Though we are using large values for near-far in a large database I
don't think it's a problem of the near clipping.

In the attached file you can see a snapshot of a two channel view with
the correct blue triangles and the missing parts.

Thanks
