[Launchpad Bug Tracker <1384393@xxxxxxxxxxxxxxxxxx>]

This bug was fixed in the package unity8 - 8.02+15.04.20150113~rtm-
0ubuntu1

---------------
unity8 (8.02+15.04.20150113~rtm-0ubuntu1) 14.09; urgency=medium

  [ Albert Astals ]
  * Use QImageReader not to load the image into memory twice
  * Don't create the whole current scope delegates, just height * 3 (LP:
    #1384393)
  * Make CroppedImageSizer async
  * Rework how we set the ranges so we get some more asynchronousity
    from item views
  * Make sure changing a scope doesn't trigger creation/destruction of
    delegates until it's finished

  [ Michael Terry ]
  * Don't block handling power events on loading the greeter's qml and the
    background image. (LP: #1383277)

Bug description:
  I think this is a generic unity8 issue that is exposed in the My
  Photos scope. This scope displays photos from the photo roll through
  mediascanner.

  Problem:
  When there are many photos, the scope does not display thumbnails for quite a while. (It may even be that no photo thumbnails display until all are loaded into memory.) This is an awkward user experience because the scope looks like nothing is happening for significant periods of time. 

  Expectation:
  Photo thumbnails would display as they arrive. (Perhaps there would be some kind of window around what is currently visible in the scope so that as soon as photos in the current scroll area, before it by some amount, and after it by some amount are in memory, they could display and the user could scroll somewhat, with the window moving appropriately.)
