Hm?? Did something change while I wasn't looking? I'd expect PDF to be handled by the postscript driver and be independent of X11. 

Could you show a transcript of exactly what you did? Maybe include capabilities() and value of dev.cur() just before plotting.

(The prototypical example is that a legend box is sized to hold the text in the font used on the screen device. Then, saving to PDF causes the box to be scaled and the font to change, but it can happen that the text now overruns the box extents.)
