This sounds like it could be caused by the DLP "rainbow effect". Do you notice the problem when the viewpoint is still or does it only appear while the viewpoint is moving?

The issue happens when the scene is stationary, the image that I posted was just one example, this problem actually occurs on just about every flat surface in the scene. Moving doesn't seem to affect it at all.

The rainbow bands become more pronounced based on the angle at which we view them. Additionally, we can see them if we view them with shutter glasses with only one channel active. The issue also occurs in non-light baked scenes, but only in cases of extreme gradients from black to white.

We will try to use a DLSR camera with a slower shutter speed to get a better image tomorrow.

Again, this sounds like a common DLP color wheel issue. The "rainbow effect" usually appears in high contrast areas. Do you notice this problem with other programs? Are your shutter glasses properly synced with the projector?
