Strange vertical line at the edge of viewport window

[Verityn]

Maybe it's always been there and I only just now noticed, but when using viewport I'm seeing a line on the far left edge of the viewable window. The line changes colors as I move my view around depending on what I'm looking at. It's almost as if it's displaying a 1 pixel wide image.

All I was doing before I noticed it was editing the EQclient.ini file to get the exact windowed resolution to fill my screen minus the taskbar. I tried changing it back to what I had before without luck and I've already deleted the UI folder/reinstalled the newest patch.
