Hello all!,

New here, I'll get right to it. Just installed Linux Mint and I'm using Cinnamon as my environment. Having issues with artifacting at the top of the desktop like this screenshot http://i.imgur.com/dNZpQon.png and along shadows around windows.

Here is a screenshot of my system http://i.imgur.com/HvvjSCU.png

I looked for a place to change drivers but couldn't find an option. I'm pretty new to all this but mostly loving the experience. Can anyone help?
