I actually get this often in WindowMaker when I'm switching to a desktop
that contains mozilla.  It takes about 5-10 seconds for mozilla to
redraw itself and start accepting input.  I haven't had time to figure
out the source, I just assumed for now that it was because the mozilla
process started swapping to disk, and swapping it back in was thrashing
things.
