Description Adam Mariš 2017-04-24 13:57:27 UTC

Comment 2 Marek Kašík 2017-05-02 16:43:33 UTC

I can not reproduce this one too with our freetype versions.

Comment 3 Huzaifa S. Sidhpurwala 2017-06-29 04:47:10 UTC

This issue arises due to the following commit:

http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=3bd79cc257499f1850a1bace21f3ae371e3b40f0

Which has not been backported to version of freetype shipped with Red Hat Enterprise Linux and Fedora, hence these versions are not affected.

Upstream versions may also not be affected, because this was a very short lived regression.
