Okay, so it turns out that the reason for these fallbacks is that some
drivers implement certain Xrender operations incorrectly (see this
thread for details:
One such case is the opensource radeon driver, the intel driver is
apparently find (at least on i965).  It's trivial to patch broken
drivers to use a server-side software fallback instead, which doesn't
cause nearly as much of performance hit as the client-side fallback that
we would have right now.  It'd be nice to get a few more data-points
(especially from users of the closed-source ati and nvidia drivers, as
we can't patch those).

A test that would be helpful to run is attached to the following mailing list post:
For your convenience, I'm also attaching an i686 binary.  Use 'chmod +x repeat-test_i686 && ./repeat-test_i686' to run it.
