in the preamble
\pdfpagewidth=\paperwidth
\pdfpageheight=\paperheight

Otherwise it puts a non-standard size in the middle of a standard size PDF.

Assuming you are referring to the 'viewer' output, I've never come across that 
but I've not used Beamer.

I agree about ImageMagick; in fact, I forgot that for svg I've used Inkscape 
to produce the eps files.

Can you add the underlines as objects in Inkscape? Alternatively, Inkscape 
offers bold or italic. I have had occasional problems where Inkscape did not 
export all the objects to an eps. I never found out the cause but when I redid 
part of the image, it suddenly started working fine.
