Plot obliterates its y-axis !?

Yesterday, Tim Trudgian posted a query about finding a maximum of a particular function. He mentioned two plots: Plot[Abs[Zeta[1/2 + I*t]/t^(1/4)], {t, 3, 10^5}, PlotRange -> Full] Plot[Abs[Zeta[1/2 + I*t]/t^(1/4)], {t, 3, 10^6}, PlotRange -> Full] This led me to try this: Plot[Abs[Zeta[1/2 + I*t]/t^(1/4)], {t, 35000, 50000}, PlotRange -> Full] which (unlike the first two) seems to exhibit a bug in v9.0.1: The area of the graph overwrites the area of the y-axis (tick marks and labels). Furthermore, Plot[Abs[Zeta[1/2 + I*t]/t^(1/4)], {t, 35000, 45000}, PlotRange -> Full] yields an even uglier plot (if that can be possible). What is going on here?
