In-Game Resolution messed up. (Fixed?)

[Hatsodoom 0]

When I open up the game, before I even log in, the screen is stretched out from left to right and the sides of the game screen are cut off completely. Changing the resolution in game does nothing. The screen was fine last time I played a month or two ago. Does my copy of retail WoW have something to do with it?

 

Edit: I somehow fixed it, no idea how...

On Windows, they share some registry settings.
