I'm running PA from steam in ubuntu 14.04. The game is pretty much unplayable for me, I used to get random lockups where the UI would freeze and I couldn't select any units, but I could still kind of scroll the map. The only thing I could do to fix this was close and reconnect. I just updated today to build 80187 and the problem is slightly different, but worse. It will freeze and I won't be able to select anything, but then when I close PA and reconnect to the game I can't see any units until the game is over. I run the game from steam with the --software-ui flag. I've got an AMD HD6850 graphics card using proprietry drivers. Any help with this would be awesome!
