Hmm. Well nothing graphical has changed in X recently (there's been some synaptics fixes, but that wouldn't cause this.) However, the fact that it shows up in photos but not screenshots fairly strongly suggests a video driver issue rather than, say, a compositing bug.
Nothing indicative in the logs (for corruption bugs there usually isn't though). The fglrx installation looks fine. I do notice in your xorg.conf there's some things set, like TargetRefresh. I don't know what that parameter does, so you might try commenting it out to see if it has any effect. Everything else looks normal. (Btw, you may be able to run fglrx with no xorg.conf now; that might be worth testing, but be prepared to copy it back in place in case X doesn't boot.)
Can you tell me more about the symptoms? Does the corruption show up 100% of the time, or only in certain apps? Is it only associated with text fonts? Does it always look the same as in the photo, or does it vary?
Can you reproduce this behavior with Unity2D or Gnome Classic (no effects)?
If you disable fglrx and boot with -ati, does the corruption still occur?
