+ [Impact]
+ 
  I switched away from the fullscreen crusaders king II game (to different
  workspace).
  
  When I tried to return back to the workspace where I left the game it
  was minimized.
  
  Switching to the minimized game resulted to a resolution switch to
  1024x768 even tough game was originally 1600x900. (The game selected
  1024x768 automatically when launched frist time)
  
  During the switching compiz decided to crash.
  
  I had enabled extra indicators in use were time/calendar, sound,
  battery, messaging, keyboard layout, network (mobile broadband in use),
  banshee and steam.
