Is this a bug in Safari?

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?

I don't have this issue on any of my macs - 2007 mini, 2010 mba, 2011 mbp, all running fully patched lion...

I'm running a late 2008 Aluminum Macbook with a fully updated OS X Lion. Is it possible that some of my extensions are impacting it? I currently have about 5 extensions installed.

Ok...so I tried turning all of my extensions off, and I still had the problem, so I don't think those are the issue. Also, I am NOT running in 32-bit mode, if that makes any difference.
