Hi all!
I was rendering a clip today and noticed that the final render exhibited ugly 'pixelation' and a change in texture appearance which was never there in the iclone preview (quality set on high) 
After some testing it turned out that these distortions appeared in the render only when supersampling was enabled in the render options, with 3x3 creating worse effects than 2x2.
Also, the bump mapping seemed changed, as if the texture had shrunk.
You can see it on the pyramid sides, with the blocky pixelation most visible on the left wall. It is much more obvious when played back in a video.

I assume it has something to do with transparent / reflecting / refracting textures. The flickering artifacts simply ruin the render - any ideas how to stop this from happening?

Fine - Iclone view / supersampling turned off in render:


 
Broken - Supersampling turned on, 3x3:

There are a few issues with the render engines super sampling..... I hope they fix it soon ........

I actually recommend rendering out "preview" mode. It's much faster, and much more WYSIWYG.

It's subtle, but the final render will give you better anti-aliasing and probably some other visual quality advantages. (I am not an expert, I just compared a preview and a final render.) Regardless, super-sampling should not cause any artifacts.

I literally got the same problem, after rending overnight on 3 X 3 Supersampling with every single setting on max, only to find several instances of this pixelation.

In the example below, look to the left of the girl's head, by the Eureka's Castle dvd box. That's definitely not there in the preview. Only when I Supersample.
