I have the same bug in https://bugs.launchpad.net/notify-osd/+bug/462490.
Also i have the same bug with yakuake https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/462549.
My solution:
1. sudo init 1 # for exiting from Xorg
2. # choose root shell in menu
3. Xorg -configure # make default config of Xorg
4. cp /root/xorg.conf.new /etc/X11/xorg.conf
5. nano /etc/X11/xorg.conf
6. # change line from
#Option "AccelMethod" # <str>
into
Option "AccelMethod" "EXA" # <str>
7. # F3 and F2
8. init 3 # or reboot
