I noticed that Fade In / Out, and even Fly transition between pictures following each other in a region is not happening correctly.
The transition is not done between the current picture and the next picture, but is done bewteen the current picture and the background, and then between the background and the next. This looks dull.
For example when you use Fly Out / Fly In, the previous picture flies out to the background, and the next one flies in on top of background.
The correct way would be to both start flying at once, looking like the next picture is pushing off the sceen the previous one.
If you just use Fly In, the previous picture disappears, and the next one flies in above the background.
The correct way would be to fly in on top of the previous picture.
If you just use fade in, the previous picture disappears, and the next one fades in from the background. The correct way would be to fade from the previous picture.
All this on the latest CMS 1.7.4 and the latest available Android client (.R55).
