Which value(s) exactly are you looking at in htop?

Assuming the memory is actually used by the X server process, can you
try to find out where it's allocated from? Running the X server
(preferably with xserver-xorg-core-dbg installed) in valgrind
--leak-check=full might be a start, though something like odin
(http://cgit.freedesktop.org/~ickle/odin) or memprof may be necessary if
the memory is freed during X server shutdown.
