I've tried this with a couple of 1-page PDFs produced
using XeTeX, and find no such discrepancy in the sizes:

plain: 597.51227pt, 845.04712pt
<use  "ruby.pdf" >
latex: 597.51227pt, 845.04712pt


plain: 597.5022pt, 844.9768pt
<use  "primeprime.pdf" >
latex: 597.5022pt, 844.9768pt

And I get essentially the same (roughly 1 in 10 million)
sizes using pdfTeX as the engine.

   <ruby.pdf, id=1, 597.51233pt x 845.0471pt> <use ruby.pdf>
   <primeprime.pdf, id=1, 597.50229pt x 844.97684pt> <use  
primeprime.pdf>

Can you supply the  dummy.pdf  that you used?

Fixing what?
This is the same version that I'm using.
What exactly are you claiming is wrong, and where is
the evidence to support that view?


Maybe my XeTeX version isn't the most recent; viz.

   This is XeTeXk, Version 3.1415926-2.2-0.999.7 (Web2C 7.5.6)

What are you using?


The LaTeX "graphics driver" is just an interface to the
XeTeX primitive, so both *should* give the same result
--- unless somehow an extra space character is getting
inserted somewhere. If this is so, then it's not happening
in my version of  xetex.def . Send me what you have, so that
I can do a  diff  to check whether somehow it has become
different after packaging and unpacking again.
