First of all, verify using something like xrestop that it's not actually
a client leaking references to the wallpaper pixmaps.
Even if that's ruled out, freeing memory that was allocated from the
heap can't always be returned to the system immediately because the heap
can only shrink down to the highest allocation still in use. If that's
the case, it should still be able to re-use a gap sometimes, especially
when you switch to a smaller wallpaper, in which case the memory usage
reported for the X server shouldn't increase.
I'm curious as to which of these might apply to your situation, if any.
