I can confirm that this problem is still present in Ubuntu 11.10.
Except this time it's the _grid_ that gets cut-off.
In addition, the menu now appears to work when the app is F11'd, but the close/mini/maxi buttons disappear. And alt-tabbing out while this is happening results in all other windows missing those buttons too, similarly to how your other apps' menus were obstructed by the grid.
