Since I've seen a couple inquiries and/or bugs, I'll just reiterate that the UI is still in a state of flux. At this point the majority of the Windows changes have landed on trunk, except for the browser actions container, but Mac and especially Linux may show problems (for example, we just discovered an image bug that makes the Linux omnibox elements look "crossed out").
The right people are on top of all these areas, so you need not file bugs yet; just have patience :)
