Strange "stair-effect" in render

[pnavarra]

I've noticed one thing :
When I modify a material and render directly, I've got a strange result in the material rendering : like some big stairs.
When I do "ctrl+S" in SU, and render just after : the result is Ok....strange.

interesting - so your saying when you save the file its fine? Or does just the action of bringing up the save dialog fix the problem?
