Comment 7 for bug 1046667

What you see is the expected artwork (http://en.wikipedia.org/wiki/Test_card it looks like that to me). And I remember that at least one other tester experienced this and asked on the irc channel whether it was the expected artwork, and was confirmed that.

(I guess people are so used to graphical corruptions on ubuntu that they don't think it can be done on purpose :P)
