Unless view_rect of the master device is exactly a golden rectangle, then the Spiral display will not completely fill the view. On slave devices, the display is set to fit the master rect correctly, which means that the empty areas around the Spiral display will also appear empty.
It would be great to override the aspectRatio and view_rect so that the slave's Spiral display has the same aspect as the master's but it fills the slave's screen better.
