If you installed
infinality-bundle or the patched
freetype2-infinality you'll most likely recently have run into an error relating to the
harfbuzz package (>= 1.4.1-1), specifically something like:
/usr/lib/libharfbuzz.so.0: undefined symbol: FT_Get_Var_Blend_Coordinates.
This is because the packages provided by the Infinality repositories or even the
freetype2-infinality on AUR are and have been outdated for quite some time, since infinality-bundle's creator, bohoomil, has been missing/unresponsive for the past few months.
freetype2 since has gotten new features and a changed ABI, one of which is a symbol named
FT_Get_Var_Blend_Coordinates which the updated
libharfbuzz tries to reference.
What this means for you is: you'll need a
freetype2 version >=
2.7.1 where this change was initially introduced. Since the future of the
infinality-bundle is uncertain this is a good time as any to bite the bullet and remove it completely from your system until more is known. The font rendering won't be exactly the same, but with a few tweaks it will at least be similar.
