Well, I called Apple and they gave me the option to send it in. However, since it isn't something that effects anything other than the solid backgrounds, which I never use, I opted to just keep it, log my problem on their system and if gets worse, I will send it in. I have AppleCare, so I am not too worried.
I saw one other person, on Apple's discussion boards, noticing this issue. Anyone else notice this? Select a solid background and check it out.
