I managed to get through the unreadable pop-ups by clicking on random buttons until it worked. Please note that the xorg.conf reported above is one I just added to try the workaround mentioned in comment #5, I did not have any xorg.conf set up at the time the bug appeared. I just thought I'd give reporting the error another try before rebooting to get a useable system back.

This does not affect xterm, but it does affect any GTK apps, firefox, etc. xfce-panel vanishes, although it's still responding to mouse-clicks. Newly opened menus are grey rectangles. The lines underlining menu hotkeys do NOT disappear. In the attached screenshot, you can clearly see which buttons I have waved the mouse over, and which I have not.
