--- Comment #7 from Chris Wilson <chris at chris-wilson.co.uk> ---
Hmm, it is doing full-screen updates via DRI3. You can try disabling DRI3
(xorg.conf, section Device, Option "DRI" "2") or hacking out that path in DRI2.
Meanwhile, time to think about what is actually happening and why DRI3 clients
are most affected.
