As stated in comment #62, Offscreen Pixmaps with XAA are, at best, a performance loss, and at worst cause rendering problems like here. There isn't anything that Firefox can do about this; instead, we'll relnote it and move on.
While I agree that not all users will upgrade their distro right away, they can all set XAANoOffscreenPixmaps in their x configs.
So, ->INVALID, on account of not being a gecko bug.
