File 109865.pdf is displayed slightly different by Evince, compared to other viewers. The top-left logo is brighter, with horizontal lines going across it.
I have tested that on Ubuntu 15.10, with Evince 3.16.1.
The file is "109865.pdf", from Govdocs1 data set (http://digitalcorpora.org/corpora/govdocs)
The file can be found in the following archive: http://digitalcorpora.org/corp/files/govdocs1/zipfiles/109.zip
I would be grateful for confirming.

Evince 3.21/Poppler 0.46.0 side by side with Acrobat Reader
This is a screenshot side by side of Evince and Acrobat Reader rendering the same document.
I do not see major difference.
Beware that Ubuntu 15.10 ships poppler 0.33. Poppler is the library used by Evince to render PDF. Since 0.33 there have been many bugs fixed.
Please, try with a newer version of poppler and let us know if you can reproduce it the issue then.

from pdftocairo 0.47.0
I see some odd horizontal banding, but it's only visible on higher zoom levels. Attached is the output from pdftocairo version 0.47.0, at 200x200 ppi. Since this looks like a bug in poppler, please follow the instructions at https://wiki.gnome.org/Apps/Evince/PopplerBugs#poppler and open a bug for poppler's cairo backend.
