Like the title says, I just upgraded to 12.04, I know it is only beta but I'm having problems with the Unity bar and the panel with the menus. First the Unity bar is acting very sluggish..I really don't know how to explain it. Also with the menu at the top, it keeps a strange little black bar on everything, even across my tabs in Firefox, it also doesn't let me see any of the menus, well they flicker and you sort of have to guess where everything is.

I'm at a loss, I've already ran updates a couple of times to see if I missed something. I really hope I don't have to completely redo my whole Ubuntu setup.

Any help would be greatly appreciated.
