The throbber next to the Creating Your Account label is stretched vertically, as is the one next to "Signing you in", "Synchronizing your data", etc. on the Finish page. It looks like this bug is Linux-specific (or possibly Linux and Windows), as the throbbers look fine on the Mac.
P3 for 0.3.
We've rewritten this UI at least twice now, so resolving WFM. Please file a new bug if there is still a problem.
