hmm, unfortunately, restarting compiz seems to have gotten rid of the
dead zone/invisible window. I did try xwininfo before restarting
compiz (but forgot to grab the output!), and the shape was very close
to that of the switcher window. If this problem is well-known, is there
something I can do to try to trigger the bug again, after which I will
report back w/ the xwininfo output?
