My 2.34 seems to render at very low color depth. Images are striped, like a bitmap converted to 256-colour file. It looks like a hipsometric map.
I see no color depth controls in the program. I seeked for the answer in literature, but I found nothing. Moreover, the manual [Blender Manual 2.3, chapter “Your first animation in 30+30 minutes”] says nothing about setting such parameters of the renderer and shows a well-rendered image; when I exactly reproduce the procedure, I get that poor image again.
Any ideas what is it and how to fix it welcome.
