There are quite a lot of variables involved there. It could be a problem
with X client libs on debian (unlikely) or some problem with Cygwin's X
server. Have you tried the same code on a local display on debian? Does
a similar C/Gtk+ program give the same results?

It'd be useful to try those experiments to see if it really is a fault
in GHC or Gtk2Hs rather than in Gtk+ or the X libs/server combo you are
using.
