This has been my experience with it. For a quick preview I toggle on a 1 pixel solid to force a redraw.

Subject: [AE] Element 3D flickering textures
I'm working with models of cell phones in Element 3d, and using a separate comp to animate the screen texture. Sometimes when I render, my screen texture goes completely white for a frame. Is there some sort of cache setting I need to use
to avoid this? I ran the AE update announced last week and still have issues.
