Zippy Sands

Actually I tried clearing the cache and even deleted the cache physically to avoid corruoted textures. I know the texture is fine because I placed it on a noc prim with a script and it renders correctly. There is some property of these prims that thw video driver must not be handling properly. Thanks for your ideas.

I just upgraded the video driver of my ATI Radeon HD 5800. Under viewer 2.7.1 (232828) all seems fine except for items rezzed from the Linden Library of plants and trees, they all switch rapidly from a properly rezzed texture to a pixelated texture. New driver works fine with all other prims and textures. New driver also works fine with third party viewer. If I roll the driver back all is well again. What is different about these prims that they fail to rezz properly?
