Answering my own question: it seems part of the issue is that the input image needs BlackOutside - I think I knew that from ages ago? We are doing a per pixel filtering operation (like Convolve), so that makes some sense. Also, I know there were some nice BlinkScript bug fixes in 10.0v4 so maybe there is a vast performance difference in certain situations.
