Since extra expose events are no longer generated during window unredirection, the window contents must be preserved by the server. So copy the window contents back from the pixmap. The copy can only be done after the clips have been recomputed, so delay the copy and the pixmap destruction until ValidateTree is done. Window borders are restored by HandleExposures and thus don't need to be copied back. Signed-off-by: Ville Syrjälä <ville.syrjala@nokia.com> Reviewed-by: Daniel Stone <daniel@fooishbar.org>
X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
