I will also check your suggestions about window redrawing. I found out that a call to force-output on the pane will do the redraw on my system (Linux/X11).
Out of curiousity, which implementation of lisp are you using? McCLIM is supposed to flush the CLX buffers before going to sleep to wait for events, but this is one of the areas where threaded/unthreaded builds of McCLIM differ, and my impression is that all the active developers use lisps with threading enabled, so the single process path doesn't get tested so often. Maybe it got overlooked.
