Xinerama + XCopyArea/Xdamage
Submitted by Anton Fedorov

XCopyArea copies blank from second monitor. Also, seems that Xdamage doesn't produce messages for changes on second monitor.
As result, correctly working in single-screen setups applications fail to work on xinerama setups.
F.e., vino ( http://bugzilla.gnome.org/show_bug.cgi?id=346258 ) shows completely blank second screen, and if disable XCoypArea, it shows no changes on second screen (seems, with no Xdamage information on it).
