I don't know exactly what this program is supposed to do, but here's
what it does right now, on GM45 and F13 with -linus
be1066bbcd443a65df312fdecea7e4959adedb45 (approx 2.6.34-rc6).

(Note: I have an extra patch to turn off all digital outputs except
LVDS -- I still need that to use my laptop reliably.)

compiz, no -indirect: solid color.
metacity, no -indirect: annoying flashing.
metacity, -indirect: annoying flashing.
compiz, -indirect: solid color.

But last time I ran it, X blew up quite thoroughly - no caps lock, no
VT switching, and no sysrq+r response.  sysrq+k killed X, but after a
couple rounds, X wouldn't respond without lagging after restarting it.
