I have only had this problem with Guild Wars, other games are fine. My problem is the ingame text is underlined with artifacts. I haven't changed any settings since Oct beta. This just started happening about a week ago. I haven't changed any drivers so that can't be it.
i took a screenshot but can't find a free place that will host the image since it's over 2mb
weird colored lines/dots under ingame text
