Same here. My card is intel gma. I saw the problem (and reported) in linux mint too. I only see this bug in the 9.10 generation. Sometimes the icon is an empty space, but usually, replaced by a distorted version of another one. But in my case it's not just the notification area, but once it was the "computer temperature monitor" too, as you can see in my scereenshot. However, mainly it's the network icon. My system is an i386 karmic and I use compiz too.
