[Bug 2137825] fontconfig 2.14.1 breaks hinting

--- Comment #1 from Akira TAGOH  ---
Which desktop are you using? 2.14.1 enables 10-sub-pixel-rgb.conf by default
but only when it isn't set anywhere else. if it isn't comfortable for your
monitor, you may want to enable other sub-pixel antialiasing option from either
of 10-sub-pixel-*.conf into your config.
