A strange Leopard glitch

This is very strange, and it only seems to happen with fullscreen apps. When it enters full screen mode, the dock glitches up. At first I thought that it only happened with EV Nova, but then I found that it also happened with a pinball game that I was playing. Strange. Resizing the dock to its smallest size and then back repairs the left side and then opening each stack individually repairs the right. I normally just type "killall dock" into a console, but I thought that I should document this glitch.
