Description Daniel Kaplun 2008-09-21 23:01:07 UTC 
My screen resolution is 1280x1024 and I have selected my horizontal gradient be from #222222 to #444444. There are 0x22 (34 decimal) distinct values, and that is definitely not enough to be smooth.

I recommend dithering of some sort.

Reassigning to Gnome-Desktop.
Comment 2 Federico Mena Quintero 2009-12-04 21:20:27 UTC 
Definitely gnome-love for someone with a background in graphics.  The GIMP dithers gradients; you can probably use that code as a reference.
Comment 3 Federico Mena Quintero 2009-12-04 21:30:32 UTC 
Look in gimp/app/core/gimpdrawable-blend.c

Marking as duplicate of bug #687650 which has a patch implementing dithering.
