Description of problem:
Best example is comparing the Solar plugin booted with vga=794 vs. vga=795;
with vga=794 it's pretty banded.
Version-Release number of selected component (if applicable):
This is with solar or spinfinity?
We definitely dither gradients.
I noticed it with solar. I'm not sure spinfinity uses enough colors to matter.
So what's probably going on here is solar uses a background image, while spinfinity uses a dithered generated gradient.
We should either dither the background image or give it a lot of alpha and overlay it on a gradient.
