What happens if you add a clear patch? Sounds like depth buffer abuse, as in the depth buffer's not getting cleared so future frames fail the depth test from previous frames. You can simulate this in the Editor by pressing cmd-K on the viewer -- this disables background erasing (how QCView operates "in the wild"). If adding a clear patch helps, you'll want to add GL_DEPTH_BUFFER_BIT to your glClear call in your patch (and also set glClearDepth to 1.0, and then restore the previous value when you're done).
