I just installed KDE to try it as an alternative to GNOME 3. In general, it works, but there are some odd menu backgrounds. Here's an example of what I see when I try to use the panel menu.

Ok, looks like the link is not working now... What I see is a pop-up box that is mostly black, with some vertical and horizontal lines in a rough grid. If I move the mouse pointer over the box, text may appear and I can click to get submenus.
