Version: (using KDE 4.4.1) OS: Linux Installed from: openSUSE RPMs Add a new panel. If you have one panel at the bottom, it appears at the top of the screen. Maximize the panel. It becomes ugly (half black) if compositing is disabled, like the screenshot I attach.
Created attachment 41592 [details] Screenshot
Also, if the desktop cashew is at the top corner or at the top of the screen, the panel hides it instead of moving it below the panel like windows.
