Strange vertical line at the edge of viewport window
 

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.

perhaps edit in the "eqclient.ini" file the value of "WindowedModeXOffset=xx" minus 1 ?

so the window will go 1 pixel to the left

That's a great idea, thank you. I'm going to try that if reinstalling the original ini file doesn't do the trick.
