Binary package hint: xorg

Since updating to Maverick I've noticed that the display becomes somewhat corrupted after resuming from hibernate on my laptop. It looks like the X server's cached images have become corrupt (guess!). It starts out small, but after a few cycles text becomes totally unreadable.

* It's mostly text which is corrupt, and each instance of the same character looks similarly garbled
* All applications are affected - eg terminal, Firefox, chromium, apport-gtk, the GNOME menus
* Changing the font (eg by changing to "Monochrome" from "Best shapes" in the Appearance Settings->Font makes many things look better, but revert to being unreadable after switching back
* Changing the font size in the application (terminal, Firefox) also temporarily fixes the issue
* Some images in Firefox also become garbled, but recover after a forced reload.

Let me know what I can do to further diagnose the issue; I'm happy to run stuff in a debugger etc. but am not familiar with the X server etc.
