To add a little more detail to Wyatt's answer, what is happening is that the "divider" image and the new "selected" image are changed instantly on touchUp, but the previously-selected segment's transition from the "selected" image to the "unselected" image is performed via an animated crossfade.

If you have a wide "divider" image with high contrast between the "divider" image and the "selected" image, this leads to an annoying flash.
