Hi,
I've got video artifacts in game. They are located at the bottom and right part of the screen, looks like some refraction and ~10 pixels thick.

On in-game screenshot they can be easily observed on banner (bottom left corner) - zoom picture in any editor to 400%.
It seems that panel is not affected - bottom right corner where End Turn button is.
After exiting to the Main Menu artifact is seen better. Now there are green lines with some color distortions.

Game resolution - 1280x1024. All video settings at max.
Some info on my PC.
