Fonts problem on the machines used for tor browser testing
Lunar noticed that the screenshots of the fa version of the tor browser look pretty bad: https://people.torproject.org/~boklm/tbbtests/r/3.6.3-5242b-Fedora20-x86_64/results-tor-browser-linux64-3.6.3_fa.tar.xz/screenshots-1.png
I don't have this problem when running the fa tor browser on my computer, so it seems to be a font problem on the machine used for the tests.
