I believe the problem is that you are making a gray gradient (which means that all three colors are changing equally). This means that you have only 256 levels available to render the gradient. Then you are trying to produce a gradient from value 84 to 129, which are only 55 steps, over a distance of couple of 100 pixels - this causes the banding. I may be wrong here - I haven't used it yet - but I believe GEGL provides you with a lot more precision in the colors. You may not be able to see it on the screen, as your monitor probably has the same 256 level limit, and you'll have to use a special output format for the same reason (eg. 16 bit PNG). This kind of problem frequently appears in the sky part of images, the the blue gradient can present a real challenge.
