Perhaps GV do not take same bounding boxes into account as other viewers 
do, and simply show where there is content, disregarding where there is 
instructions that the content (or page or printable area or whatever the 
various boxes are for) dictate.

All I know is that two different PDF renderers agree on an output which 
makes me blame the input as more likely flawed than (one of) those 
renderers.

To be potentially helpful (to others than me: I am convinced already) 
you need to figure out it in fact you have found a 3rd renderer proving 
my point or you are just indirectly proving my point using one of those 
same renderers.

I don't see how it matters if Poppler stores on disk or takes a coffee 
break before it presents its rendering - fact is it somehow produces 
same skewed result as Ghostscript does, from an independent codebase.

Sorry, I cannot help debug TeX.

Perhaps you simply need to initially page defaults properly, but that's 
just a wild guess.  I honestly cannot help you further.
