Sometimes improvements to the device functions may lead to such a 
phenomenon. In this case maybe since the plots are actually really 
small, some overhead matters.

A minimal reproducible example would help that someone looks into the 
details, but I doubt this is too important here. I also doubt this is 
Sweave related. Have you tried a minimal example with the pdf() device 
directly? Have you read the NEWs about changes since R-2.11.1?

Best,
Uwe Ligges
