I have similar problems with the gtkairo backend. As a quick fix I use

 (setf clim-gtkairo::*medium-type* :gdk)

wich seems to fix the redrawing problems. With :cairo as a medium type I
get serious redraw problems (mostly areas that stay black). I'm running
SBCL on Ubuntu 8.10.

No idea about your windows problems.
