Well, then we'll have to come up with some subtle psychological twist to let people know. Perhaps the overlay could be of a prone person who, after 2 seconds, stands up and performs calisthenics until the still render is complete. ;-)

Or more seriously, the overlay could be present during all interactive rendering and just start "counting down" (I still prefer a clock-like wedge to a countdown, especially given that it's a short 2-second interval) when the mouse is released. That way the overlay's presence indicates interactive rendering, a modified form would indicate the still rendering is being performed, and its absence indicates that the image is a completed still rendering.
