Yup, documentviewer will sometimes show faint lines better, I find, but
it's easy to set the background colour in xpdf.

That varies, and a reader with good error messages is the easiest way to
find out.

Well, given s/would/could, try mupdf:
$ apt-cache search mupdf
mupdf - lightweight PDF viewer
mupdf-tools - commmand line tools for the MuPDF viewer
libmupdf-dev - development files for the MuPDF viewer
In my case, a pdf certificate from a state authority displayed the logo
and signature in xpdf, but none of the text - not much use at all.
A quick install of mupdf not only allowed the whole document to be
displayed, but issued (a squillion times) the following error message on
stderr:
Error: Couldn't create a font for 'ABCDEE+Calibri,Bold'
Error: Found a bad table definition on true type definition, trying to continue...
after an initial:
Error: PDF file is damaged - attempting to reconstruct xref table...
I only use mupdf for problem pdf files, but it's very nifty to have on
hand.
