Incase anyone out there encountered this issue: Vindictus is running in windowed mode w/ no border, causing monitor tearing.
As I've grown tired of Battle.net's game list feature, I've developed a web-based replacement. It only shows a fraction of the current games (at least, if there's more than 10 or so). It's very limited, and game's which you know exist either will not show up or will disappear from the list within a few seconds. To my surprise no one had come up with an improved game search.
