I can confirm this bug using the nvidia-glx-new driver an compiz window manager. It seems to be a repainting problem; I usually switch to workspace/viewport 2 and back to workspace/viewport 1, which repaints the screen. Few controls (e.g. the desktop switcher applet) are repainted by hovering the mouse over them.
