Hi Brad,

I have done some work with PDL::Graphics::TriD and the only time I have noticed flicker is when my X server was configured to use software OpenGL rendering instead of the videocard's hardware rendering. If you are visualizing a large dataset or updating it with some intensive computation I might expect some lag when loading the new model, but not flicker. For example, I can throw 1,000,000 points into a model and stretch the window to 1600x1200 and rotate the plot all over the place without flicker. Doing the same thing while moving the points around generates a lot of lag between iterations, but no visible flicker.

If the hardware rendering isn't the problem, could you provide some more information about the type of visualization you are doing (large dataset, frequent updates, etc.)?
