As you can see, the background stripes image tiles left to right. This is also visible in the Community menu, and if I look very closely, Library (one pixel wide line of dark gray down the right edge).
This will be fixed in the next client beta.
Fixed for me in the latest update.
Fixed on my netbook; I'll check in a bit when I get home to see if it's fixed there.
Nothing extracted yet.
