I'm not sure as to the reason, but I am definitely seeing a similar, and
surely related, problem. After time running Rox with the pinboard
background set, X memory usage goes through the roof, redrawing
(shading, etc) becomes very slow. 

"but if you drag a window over it"

I'm assuming you meant dragging windows over the pinboard to cause a
redraw?  This doesn't seem to cause it for me; at least not fast enough
for me to notice.  For me it seems to happen directly any time I change
the background image. And, the symtoms seem to get worse over time.  I'm
not sure if this is due to killing and restarting Rox, as I've been
doing that a lot lately.

I'm also running Debian unstable.
