Currently in the world map when you switch or tab through your men, when it gets to vehicles (the new expansion is really getting annoying) the screen messes up and you can not tab any longer. Now, in battle, this just happened. I went to my sniper and tried to change her inventory. I am now stuck and can not do anything to get out of this screen and can not switch gear or do anything else. This will require a ctrl-alt-del out of game to restart from last save point.
I currently use surround which should be obvious by the screenshot, not sure if this is related.
