Weird theme issue when using an image object

[Gerard Butler]

So I used an image object for the text in my theme and gave it a drop shadow, and when testing the theme at 640x480 every time I moved the selection the image object was getting refreshed in a way where the other image wasn't disappearing so that's why it has that black blobby shadow (I just held down the down arrow key for a few seconds), but at 1600x1200 (and I'm assuming the other resolutions) the image refresh issue didn't occur.

I'm using the stock grub from Ubuntu 12.04 so I don't know if this was a bug that was already fixed or not in a later version upstream.
