Just upgraded to Raring and it went relatively smoothly except for a couple of hiccups. I'm using Gnome fallback & then auto-loading Compiz. One thing that's annoying me, though, is that the Menu Bar on the panel is run together, so that instead of saying, "Applications Places" it says, "ApplicationsPlaces." It appears to be some kind of pikey faux-tab thing and it just looks stupid. Pointers on ways to make it less stupid would be appreciated, since a search hasn't managed to pick up anything.
