I don't know how dynamic you want this to be, but if you are worried about the image buffer overflowing, you could try "dropping" captured frames if the buffer is filling up too quickly. Or if the screen is being transformed (rotated, etc.) by a behavior (not a human), then you could simply "pause" the display until each frame was written (or something else along these lines).
