Comment 115 for bug 331369

Same error here. Laptop with main screen, and a HD television screen hooked up via hdmi cable which I use to watch videos while working. Moving the tv screen from the bottom display to the top display actually fixed the notification problem, but created other problems , with Guake Terminal for instance, which I use frequently while working. The best workaround I've found so far is using the "follow-focus" method as mentioned in comment #104, however this is certainly imperfect as the notifications are now positioned slightly differently from normal which is mildly annoying though temporarily livable. Using the unofficial methods as discussed in this thread (http://askubuntu.com/questions/128474/how-to-customize-on-screen-notifications) to make notifyOSD configurable and then setting the notification positioning from "fixed" to "dynamic" actually gave more normal positioning, but unfortunately also altered the look of the notifications themselves. Perhaps I'm being picky , but I found that even more bothersome and distracting. Currently, notifications as they look and work on normal single screen setup are beautiful and draw the eye enough to do their job, but no more. In other words, nearly perfect. I really hope you will soon address this issue.

For the record, I actually have an AMD A8 'Vision' graphics card, which came with my notebook.
