Nancy, the base v4 texture has that as well and doesn't give these problems under my normal settings but...

 

Mathman, try turning your raybias on the lens down to .085 and see what happens.  I seem to be getting the problem on my base viki with the raybias over .3 (really noticable at 3.5, not so much at 3.2).  I'm guessing that's what's happening to you too.

WARK!
