double-image? (just making sure)

[madFive]

I'm getting this weird efect most of the time now, generally whenever i walk near bright lights or use the flashlight/glow-stick - it's pretty cool looking, but sometimes a little obtrusive. Just wanted to make sure whether it's supposed to be there or not. Getting a double-image overlay of the scene - kindof a less-pronounced version of the filter used during the inspect-item feature. Not really wanting to take measures to get rid of it just now, i'm mostly just curious if this was intentional or some kind of artifact from my video card...
