[poppler] invisible text rendering error

[Oliver Sander]

Hi Alexey,

can you please open a bugreport for this at https://bugs.freedesktop.org/ ?
Otherwise your issue may just fall through the cracks.  Please attach your
patch and an example document that shows the problem.

Your patch isn't easily recognizable as such.  Can you please post the
output of git diff ?

Thanks,
Oliver
