White pixels at top of screen?

[jediguitar101@yahoo.com]

I've got an image that I created for a wallpaper that's displaying a few white pixels at the top of my screen. It's not my monitor, as it's displaying other images just fine. The image in question isn't showing any issues while in GIMP...and the color at that point is the default black. Any ideas as to what might be going on? So far I've exported it as a png and a jpg. Both are displaying the same error.
