I noticed this in the last two weeks or so and it seems to have started out smaller then has became wider and wider. I first noticed it while using VLC. I asked another friend and he said it could be the way the codec is rendering the video. It started to get worse (or wider) so I figured I'd try seeing it other ways. When I boot up VMWare, I notice it as well. Same friend said it could be an issue or just VMWare.... So I just now changed the desktop wallpaper to a solid black background and I notice it still.
