On scrolling quickly through the all sites view, icons tend to get mixed up.
Its still happening as of version 0.1.31, on a different view this time.
Can't see it? Look at the first question in the image. Its this one.
Stack Overflow will go back to being agnostic in the next version update, thanks!
Update 2/25: This should be even more fixed as of version 1.0.16. It was still happening sometimes on the site selector (dropdown when selecting a site to ask a question on) and sometimes in other views, as of the new update we're using a new third party image loading library (Picasso) which seems to have fixed this from happening anywhere.
