Comment 2 for bug 390279

I have experienced similar symptoms with the Awesome bar in Firefox while running Compiz. I have never observed the issue when running Metacity. I could not reproduce the bug on first try using show desktop to try to trigger it. I have show desktop enabled but have not been using its functionality lately (due to a different bug: it misplaces windows a few desktops over sometimes).

I will disable the plugin and post if I can still reproduce this bug.

I would guess it's a z-order bug, since the Awesomebar with correct suggestions suddenly appears and works normally again if Firefox loses focus and has it restored (eg, alt-tab or clicking another titlebar and then clicking Firefox's titlebar).
