If I use any build newer than r41176(till I file this bug report), the navigation bar under the site logo ("Hots Apple Plugins" etc.) will be missing, while r41176 works fine though. While the words are missing, the links are still clickable. I consider it only a rendering problem.
p.s. Just for anyone may want to know, I'm using the new Safari 4 Public Beta.
