Hello,
Huh. I see it too in your generated outputs, and I'm running RHEL6 and
display using okular (same when I use acroread too).
I zoomed in 2400% and it's quite clear that the "ghost" lines are
connecting the vertices of the polygon that forms the letter. The letter
"o" has way more lines than the letter "l". The letter "t" is waaaaay
out there!
Weird. It does look like the different versions of the applications are
doing something differently.
The versions without the lines produces a *much* smoother letter, i.e.
the letter "o" in the "not-funny" version is completely smooth even when
zoomed in at 6400%. In the "funny" version the same letter looks quite
blocky.
Maybe the updated versions of the applications were built with a
memory-saving switch or something? (waving hands about here looking for
explanation).
cheers,
paulv
