Happens to me too. The background is too bright for me so I kept it on the default skin. I think it is that the skin was designed white and certain parts only light brown. Not sure though.
I just noticed that the top graphics on the buttons are gone except for the blog button. Will this be fixed soon or will it intend to stay like that??
Also I noticed that the User CP button isn't up there (like on the sister sites) so it makes it harder for members to go to their User CP. Can you add that button on too please??
Here is a picture:
