- Setting "Wait for vertical refresh" to "On, unless application specifies" doesn't work.
- But setting enable "Force full screen redraw (buffer swap) on repaint" in CCSM does work.

strace shows that compiz loops on
ioctl(12, 0xc00c645c, 0x7fff3791e1f0) = 0

where 12 is /dev/ati/card0

Daniel, I'd be happy to provide stack snapshots with gdb if you'd tell me how. Thanks for your help.
