Hans' MWE is not comparable, but Aditya's example (with \setupbodyfont[palatino]) compares just fine!

I can't process that here. This is a easier test:

\nopdfcompression

\setupbodyfont[dejavu]

\startTEXpage[offset=10pt]
     a % a
\stopTEXpage

Even such a minimal document cannot be compared. I have no clue how the compare is supposed to work but if a simple 'a' vs 'aa' document does not work while the files preflight ok it's probably an acrobat issue.
