When I hit the Special key and go to the "Activities Overview" Gnome screen, the cursor defaults to the search box, which is great.
When I start typing, the temporal ordering of some of the keystrokes is reversed! I try to type "test" and instead see "tets"! This doesn't happen every time, but I'd say it happens at least 1/5 times, probably more. I suspect whether it happens or not has something to do with refractory time (time in between instances of this bug), or maybe an action that resets the system into a state where this will happen again.
