Cantarell is the only font that I have seen have negative effects. As shown in 
the screenshots, other fonts appear normal, as do Monospace type fonts in terminals.

Fedora uses the font directly from upstream with no patches/features applied.

http://ftp.gnome.org/pub/GNOME/sources/cantarell-fonts/0.0/cantarell-fonts-0.0.15.tar.xz

Running "fc-query" on the file reports "fontformat: "CFF"(s)" so I assume the 
latest upstream font generates an OpenType/CFF version, but I am not a font expert.

You can find the Fedora package on the Fedora build system. If you do not have a 
system to extract the otf files I could place them somewhere.

Thank you for looking into this. There are many user reports of this issue so 
my, subjective, opinion that the Cantarell font looks "worse" is not unique.
