More input may be needed. What do you mean by "corrupt graph?" What is
your platform? What graphic card do you use? ...
I have tried the above expression on my system (64-bit Intel Core 2 Duo
Mac OS X Leopard 1.5.4 Mathematica 6.0.3), varying PlotPoints from 60 to
200 and failed to notice any "corruption."
