OpenGL renderer lighting issue

[korbainK7]

heya everyone. I been watching this project for quiet some time and you guys seem to know your deus ex stuff. I Discovered the updated open GL renderer here and have been using it for quiet a while, lately i have noticed though when i am near flickering lights in the game the area where lights are flicking have big black boxes going down the screen. I don't know if its a tearing issue or if its a buggered up setting in the deusex.ini. any help would be awsome!
