I have a GUI with two views:

 - A background 3rd party launcher application that is expensive to
render (at
   full speed, it manages 10 fps).
 - A fullscreen transparent overlay that renders some foreground items
(can manage 60fps)
   For example, see: 
http://stackoverflow.com/questions/6371432/how-to-display-a-fullscreen-type-system-alert-window
)

Is there any way I can decouple the draw rates for these views. I want
the foregound to render as fast as possible. However, as I understand
Android, if you have a transparent overlay View, then, in order to
redraw it (and have the user see the changes), you need to wait for
all of the lower items to draw first.
This limits the rate of foreground view to the slowest rate of any of
the Views it covers.

Without making changes to the 3rd party application, how can I
decouple the draw rate of the overlay so that it animates as fast as
possible?

- Thanks.
