Hi Reinhard,

You have to zoom in pretty far to get the problem to go away
completely. Whether the .pdf file is "correct" as-is is a semantic
quibble, because we have customers who will be reading the reports we
are generating in Acrobat Reader, and lines appearing and disappearing
due to rounding errors, no matter what the cause, is unprofessional.

As a short-term measure we've disabled support for row-colouring in
our reports, but we would really like to find a workaround since we do
nice things with colortbl like striping tables, etc.
