FYI, the root cause of this bug appears to be because compiz uses
XkbStateNotify, which is part of the X Keyboard Extension. Using this
extension has the unfortunate side-effect (by design) of ignoring grabs
held by other clients and still giving you key events even when you
shouldn't be receiving them. This is documented is the spec:

"As with all Xkb events, XkbStateNotify events are reported to all interested clients without regard to the current keyboard input focus or grab state."
