This seems to affect GtkChamplainEmbed[1] (and in turn Maps) badly. 
Zeeshan posted an example of this[1] to the Champlain mailing list
yesterday.

Unfortunately I'm not familiar enough with either Gdk, Clutter,
GtkClutter or Champlain to say anything about the code, but I did a
bisect of Gtk+ to see what commit introduced this and it seems to be:
  b875572 gtkwidget: Widgets are now always double-buffered

So I guess I'm hoping for some insights from someone on where I should
start looking for a solution to this. :)

Mattias
