[x11] Use root window for barriers

Browse source 
It turns out that if the barriers are set on the app window, and the app
grabs the pointer (even passively), barrier events will no longer be
sent to the app. However, creating the barriers on the root window and
the events are selected on the root window, the barrier events are sent
regardless of the grab state.
