I just upgraded to 11.04, and now most UI elements are gray and crappy looking (see screenshot).
When I first log in, the panel looks black (as Ambiance theme is supposed to look), but then after a second it turns gray and crappy-looking. Title bars of windows seem to be fine, but everything else seems messed up.
I've tried changing my theme in the "appearance" settings and it doesn't do anything besides change the title bars, and in 11.04 I can't seem to find any other settings related to this.
How can I fix this to look like it's supposed to look (default 11.04 theme)?
