Since the days of Mavericks, this annoying little Safari bug has been persistent and driving me bonkers. How to reproduce: 1. Open any website in Safari 2. Command-F 3. Choose "Show Top Sites" from the History menu 4. In the same tab/window, go to any website (Facebook.com is the best example) Now look at the top of the page; it appears to be obstructed by the browser window. Yes, I've reported the bug to Apple several times. Still nothing.
