Remove window obscurement information. 

If ACTION_OUTSIDE_EVENTS contain information about whether the touch is
obscured, then a pattern of invisible, untouchable, unfocusable
SYSTEM_ALERT_WINDOWS can be placed across the screen to determine
approximate locations of touch events without the user knowing.
