--- Comment #35 from Albert Astals Cid <tsdgeos at terra.es> ---
Had a look at a lot of files on the regtest and while most look better there
are at least 3 that look much worse when rendered with -r200 on pdftoppm than
without the patch, listing them here

altona_technical_1v2_x3.pdf columns 4 and 5 get all blurry, this does not
happen in acroread neither in the cairo outputdev

http://bugsfiles.kde.org/attachment.cgi?id=12083 page 12, there is a blocky
graph that also gets all blurry, this does not happen in acroread neither in
the cairo outputdev

File_that_i_will_attach page 7 bottom left image gets "destroyed", this
happpens a bit on both acroread and cairooutputdev, but not as massive

I'm concerned about them all, but
http://bugsfiles.kde.org/attachment.cgi?id=12083 seems like the most important
one since the clear data shown by the graph is lost.

Any idea how to fix this?
