on http://www.gamestyle.net/, the black and purple color schemes use transparent PNGs for the top left logo. In safari, these do not work as they should, and the background appears darker showing the logo separate from the bar. works fine on Camino, Firefox (Mac and PC, release + nightlies), and IE 7
I think the problem is that the PNG has an embedded gamma value.
Yes, it must have been so. Anyway, the logo now looks fine, so the issue seems to be fixed.
