Help: Stretched album art on Controller App (Android)

Hope someone can shed light or help me resolve this problem:

I use the Logitech Squeezebox Controller App on my Android devices, a Nexus 7 tablet and an Android phone. I have some album art on my LMS 7.8 that are not in the 1:1 aspect ratio. When these album art are displayed on the Squeezebox Controller App on my Android devices, the album art is stretched to fit the 1:1 aspect ratio of the App. I really want the album art to be padded or fitted, so that artists' faces are not distorted! (see stretch versus pad versus fit: http://wiki.slimdevices.com/index.ph..._side_resizing)

The non 1:1 aspect ratio art retain their original aspect ratio on my LMS web interface and on my SBTouch interface. So this problem with stretched album art only happens on the Controller App.

Anyone else using Logitech Squeezebox Controller App and what are your experience with album art on the App?

Thanks,
Leon
