Mac OS X 10.6.3 Weird screen issues. PIC

[Costumed]

Hi,

I've upgraded today to 10.6.3 and everything went just fine. There's just 1 thing.
My MacBook Air is now showing some weird 'shadow' on the left top of the screen. I've never seen this in my entire life.

Here's a screenshot. Take a look.

Can somebody please explain how this has occurred? Why haven't I seen this before when I was on 10.6.2? How can this be fixed?

Tried shutting down your computer?
Possibly restarting?

Reboot, repair permissions with Disk Utility and create a new account. Do in that order

I had a similar issue where the top menu bar seemed messed up. A simple restart fixed the issue.

Okay, you guys are awesome. Like said before, a simple restart took all the pain away. How come I haven't thought about that .
