sna: screen corruption with glx-dock (cairo-dock)

I've been getting screen corruption since SNA was first introduced. The latest version of xf86-video-intel that I've tried is 2.20.6.
Some details about my system: Arch Linux x86_64 cairo-dock v3.0.2 xcompmgr v1.1.6 (run as xcompmgr -c) mesa 8.0.4 gpu: i915 (core i3)
The corruption is more or less as shown in the screenshot. Sometimes it's more colorful, sometimes it's completely black, but always covering about the same area in the top left corner. It happens almost every time I click on a particular menu button.
It only happens in SNA mode. It doesn't not happen with the dock is using the cairo backend (with or without SNA), only the opengl backend.
The screen goes back to normal if the corrupted area is refreshed; I usually just hit F11 in Firefox or gnome-terminal...
Please let me know what else I can provide =)
