Re: PDF displayed incorrectly by certain software

My guess is Adobe's security features are getting in your way.  Files 
have to be unprotected before any full accessibility checks can be done 
on them and the security protection adobe put in on their newer pdf 
files defeats accessibility checking when enabled.  If whatever software 
you use does not completely disable adobe's security protection, I think 
it entirely reasonable the protection at most would fail to show full 
contents of the files.
