Description Bill Nottingham 2008-10-23 16:34:54 EDT
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):

plymouth-0.6.0-0.2008.10.21.2.fc10.x86_64
Comment 1 Ray Strode [halfline] 2008-10-23 17:39:36 EDT
This is with solar or spinfinity?

We definitely dither gradients.
Comment 2 Bill Nottingham 2008-10-23 20:18:34 EDT
I noticed it with solar. I'm not sure spinfinity uses enough colors to matter.
Comment 3 Ray Strode [halfline] 2008-10-24 09:31:09 EDT
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.
