Hi there. This may be a slightly stupid question, but has anyone who uses live wallpapers noticed on iOS 8 when you close an app that at first the screen is blank and then the circles slowly fade in? It seems to do this every time I exit an app or unlock the phone. I seem to recall that in ios 7 the circles were just always there. Has anyone else experienced this? Is it just a bug that'll be fixed or did they do this on purpose for some reason? I'm using a 5S.
