Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=54168
Fix errors introducted in 863d528a9f. Said
patch does indeed remove the problematic writes to bad memory, however
it also introduces errors in the algoritm. This patch has the effect of
reverting said patch and adding an if in the proper location to catch
the out of bounds memory write without causing problems to the overall
algorithm.

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.
