Comment 2 for bug 13521

screenshot will follow this post.
to reproduce:
1. open a nautilus window (while having everything set as mentioned above).
2. maximize it by double clicking the titlebar.
-> bars
let anything else get focus -> bars will be gone
resize to normal again by double clicking the titlebar -> bars.

Actually I think this is not a metacity but a nautilus bug. Firefox and other
apps redrawn correctly. They must have missed out one redraw. But I'm no
programmer so I can't be sure :)
