during music, T! will display the visualization in the background.

you can either:
- select a visualization (can be done on the music osd)
- disable 'backgrounds > hide visualization background' in the skin settings

This is not about the background on the music playback screen. If you are playing music then go BACK to the main menu, the music changes to a mini player, but the home window background is black. All the backgrounds for the individual menus (Videos, Movies, Pictures, etc.) are black. As soon as the music is stopped, they re-appear.
