There appears to be some kind of memory leak in the soldier status screen in the battlescape, related to the wounds system. When opening the status screen for a soldier with a wound (red exclamation mark, or blue in case of treated wounds - doesn't matter in this case), it takes longer each time. After opening it 12-20 times or so, it starts taking inordinately long - 15+ seconds easily. The resource loss is persistent over several missions and only goes away when exiting and restarting the application.
By the way, is it just me, or is there no way to tell how many untreated wounds a soldier has? In the old X-Com, you got a numerical fatal wounds counter, didn't you? Also, it would be nice if mousing over the exclamation mark in the status screen during combat told you what kind of wound it is (torso, arm, leg, etc.). I'm pretty sure the position within the green square is consistent for each location, but you'd have to know them in the first place for that to be useful.
