I'm not seeing any corruption at PlotPoints->{150,150} compared to
PlotPoints->{120,120}. That's Mathematica 6.0.3 under Windows XP.
I presume the main reason you want to set the value of PlotPoints is in
order to see the poles with smaller real part. But you might try using
MaxRecursion instead of PlotPoints.
