Just tested your latest fix and it is SO smooth now. Theme works great on the Pi now.
The only minor issue is that on a lower res CRT monitor the small text at the bottom (year/manufacturer, play count, num players) is hard to read and blurry. Could there be an option to make them a little bigger? If not, no big deal. It's already pretty great.
Thanks again for the theme!
