An odd one, yes? A jpg icon is being clipped in the temporary fence. A scroll bar DOES show up, the fences are locked, and the problem is incosistent (the months fence has multiple icons within it as well)
Perhaps that is intentional. I hope not, because I like that with the months fence, I can only see one icon at a time, and as I scroll, it displays a new row of icons on every scroll trigger. It's a much cleaner way of displaying the icons.
