I'm running version 188.8.131.52.g9977a14b.
1. Launch Spotify
2. Switch to fullscreen mode
3. Scroll down in any of the views (Browse or Activity or your Playlists, whatever)
4. Switch to another application (command+tab for example)
5. Switch back to Spotify
6. Your back at the top of your view
It gets very annoying if you got a long playlist for example. You want to find something from your playlist and you scroll down, switch to another window for a second, switch back and your're back at the top and got to start scrolling again.
