What you are most likely experiencing is a driver issue upon shutdown. Since it is only at shutdown it can most likely be disregarded as an anomolie that should not cause any issues longterm.
But, as I myself would also find this quite annoying and want to get rid of it, ( read "fix it" ), if you could give me a model number for your laptop, I would be more than willing to see if there is a more up to date driver for your video.
