I posted in here awhile ago about how sometimes my computer would just randomly lock up and the screen would become all.. pixelated or whatever.. this time I was able to get a screenshot of it before it locked up.. this can also happen when I'm not playing flash video, so I don't assume it's flash locking up my macbook pro.. again I know this is a repost, but with a picture to go along with it, maybe you can get a better idea of what I'm talking about.
