Bug details:

There is an rectangle in the center of the difference image.
The left input image(the gray one) is smaller than the rgb image when displayed in the window

The reported bug is not true. As we open the images with Gwenview (an image viewer), the region that outside of the image is "gray". Thus, the "left image" is actually with black pixels.
