Is everyone using 1080p for their resolution? I suspect I was having the problem because 1920x1080 does not appear as a resolution in the default list. It only shows up when I set the game to fullscreen. Changing the settings to default getting into the game (into the Social Tavern) seems to work. After that I can reset to 1080p with no problems. My card is an nVidia GeForce GTX Titan.
