Application menu doesn't show up on Alt

[Suor]

I have default global application menu and when I press <Alt> nothing happens. I expect to menu appear instead of application title.

Hot keys like <Alt>+<f> do work, but global menu remains hidden and popups appear misplaced, see screenshot.

Bug appeared after upgrade to 13.10, global menu used to work as expected in earlier ubuntus. I also tried a fresh install of saucy in virtualbox, it has the same bug.

There is no mention of menu not showing on Alt press in original bug.
