Spotify doesn't work perfectly in Linux, and it's always lagging behind and does weird things. Take for example a locked screen with spotify in the background. When you wake the screen and log in, Spotify often decided to curl up in a corner of the screen because apparently it tried to get the screen size from a locked, sleeping screen, which is 0. Or maybe it was one of the 10 API's between Spotify and the screen data it wanted...
