just sent a serieс of patches to the mailing list that would address
some of the issues.

a couple of notes here. apparently ATM we can render the profile in
vector graphics, which would allow you to take good screenshots from
PDF at any size, but our tables remain in raster. this is basically a
topic i would like to discuss with others - i.e. if we should leave
the tables in raster but make the profile in vector and what is
possible in Qt and what-not.

for now everything is raster (pixelated) and i suggest that you print
at a high DPI and only take screenshots when the print preview or PDF
is at 100% view size. following a resize on such a screenshot will
then have some distortion and/or blur due to interpolation and/or
filtering.
