This is reproducible. Remove the notification area from the top panel then re-add it and the icons are restored to normal. Reboot and the error often comes back.

I do not think it is related to video drivers as I see it on two systems right now, one laptop with Intel video, desktop with nvidia - both do the same despite different chipsets and drivers.

Effect can be eliminated if the notification area is moved to the another panel. On my desktop I moved it to the bottom, on the laptop I use AWN and included it there as a widget, in both it now runs perfectly normal.
On either, if I move the notification area back to the default install location (top panel, right side) the error returns.

There is a thread on the forums with multiple users reporting the same bug on many varied setups.
