Screen Flickering

Q: My application animates moving geometries. Recently, I'm seeing a lot of screen flicker, and faces of geometries which should be behind other faces are showing through. What gives?

A: Sounds like you may have doubleBuffering turned off. Turn it on by calling Q3DrawContext_SetDoubleBufferState.

It could also be a result of having excessively large difference between Hither and Yon. Experiment with greater hither values and smaller yon values to see if the bleed-through goes away.
