Posted this at the mod's forum, but I might as well cross post to see if anyone here has any ideas.

I'm pretty sure I installed everything correctly for the wide screen mod, but I've noticed an odd issue with the game now with or without GUI replacement mods installed. This is from playing at 1280x768.

If you enlarge the picture you'll see these vertical bar lines going through the shadows. When playing the game they are always there. It's nothing game breaking but it's really, really annoying and I was wondering if there was a way to get rid of them short of going to a lower resolution?

I fixed it. I went ahead and downloaded Bg2 and did the full BGT mod install. That seems to have fixed the issue I was having.
