Vista - Is anyone else's User Account picture faded white at the top?

I went to change the default picture for my user account which is the daffodil (or whatever orange flower with yellow pollen in the middle is) to a custom picture, and I noticed that towards the top of the picture it looks like it fades to white. I went back to select one of the default pictures, and this occurs with the default pictures as well. Is there an option to turn this off, because it's really annoying. Here is a picture to help show what I mean. I just did a fresh re-install, but I don't remember that white fade being added to my picture from before. My laptop came pre-optimized by Geek Squad people at Best Buy, so maybe they did something that was able to turn that off, or maybe I just don't remember the white fade being there, but it was there all along.
