Comment 159 for bug 438868

This bug affects Totem in Ubuntu and Debian Squeeze- after the screensaver has appeared, full screen menus disappear when hovered over, rather than appearing as they should.

At least one other person has the same problem because they filed a bug for it:

The bug also affects Firefox 4 with all menus disappearing when hovered over. I have observed this in Debian Squeeze, and it's also happening on Ubuntu.

In both Totem and Firefox, disabling Compiz fixes the problem.
