So sort of recently, I installed AL and started it up. So far so good. As soon as I loaded a neighborhood up I was greeted with something like this:

What the hell?!

I was kind of shocked because I have never experienced this in all my time of simming. So I exited the game, installed new drivers thinking that would help some and then, this happened:

It got so bad after a while, that I wasn't even able to exit the game.
Are those white squares birds?!!

Mind you, this doesn't happen on another windows account when I load the game. I really want to fix this problem ASAP so I can get back to playing my families.
I currently using a Radeon 9250.
