Black boxes and screenshot

[Sambie]

Every time I take a screenshot of my desktop using the compiz cube, it gives me a couple of black boxes. I will attach a screenshot so you can clearly see what I'm talking about.


Can someone help me to possibly fix this problem? how can I stop the black boxes from appearing on the screenshot?

kind of looks like some more i have seen with nvidia cards
a driver update or roll back depending on what driver you
have may solve this for you.
