Take a look at the screenshot below.
As you can see there is some strange stuff going on with the Bookmarks Bar. Instead of showing the actual bookmarks (which I have around 12 of) I have this weird, plain, gray bar underneath. This only happens (at least as far as I know) when I'm in full screen and it disappears and returns to normal when I exit fullscreen and then enter it again. Also, strangely this doesn't always happen: maybe once every few days. Anyone have any ideas of how to fix this, or is it just a bug?
