This can be caused by certain overhead LED lights. Sometimes this flicker is visible directly, and other times it can be more subtle. If you notice that the view of the workpiece through Origin's display is flickering, or that the tape visibility indicator is changing state while not moving Origin, then your overhead LED lights may be to blame. Try turning off your lights to see if the issue goes away. If it does, consider replacing your lights or moving to a different light source. Incandescent lights, flicker-free LEDs, and sun light won't cause this issue. For more information about workspace lighting, see this support article.
