I've noticed lately that iTunes on my Mac has had a couple of weird graphics defects to do with its windows. Firstly, the main window had an odd bug with its corners where instead of being rounded they had strange squared-off grey bits behind them. This bug was corrected after a restart. Secondly, the equaliser window now has a weird issue with its background textures. It's no longer a smooth gradient, as with the rest of Leopard. It's now as it appears in the attached image. This bug, however, hasn't been fixed with a restart. Although these aren't huge problems, I thought they were a little strange.
