Comment 17 for bug 1081702

My background is computer graphics. I've been on that industry for about 20 years.

There's no way wallpapers with so much gradients on a limited color range that cover a big screen area at the same time will look good on most screens today. Not only laptops use mainly 6-bit panels. There are also many cheap desktop monitors that do the same. Some dither properly, others don't. But I even question that big screens using 8bit per channel will properly show these gradients too. As a matter of fact, this wallpaper might be used to test an 8bit monitor's quality... ;-)

Until we all have a 10bit per channel workflow (and that won't happen in a long long time) the real solution is letting the artists know the limitations of gradients -especially those on short color ranges using big screen areas- and ask them for a different style of wallpapers. Non-busy wallpapers doesn't mean "very simple gradients with tons of blur". Of course, management at Canonical should be informed about this too, just in case orders to use this wallpaper style come from above.
