I realize a strange behaviour when opening this file with
zathura. I takes about 15 sec. to load it in the first place, finally the
background is not displayed. This happens with 0.1.2.2 from the debian
repository and with zathura built from git as well.
Using the mupdf plugin makes it worse - zathura fails to render the
text color (red = red).
Mupdf e.g. opens and renders this file correctly.
