By the looks of it, Parse is still downloading the image as the table view scrolls (that would be only reasonable). The behavior of not displaying until the table stops moving would appear to be a shortcoming of Parse not executing its operation using NSRunLoopCommonModes. AFNetworking gets this right.

Hi Mattt, in PFQueryTableViewController, the downloading does not start until the scrolling stops. We chose to do this because we wanted the default loading behavior to be very passive. You could verify this is indeed the behavior from the animated gif - the network activity does not start until the table finished scrolling.
