Update: Thanks Operations for blazing quick response, new FreeType is on the server and rendering should back to normal after cache invalidated.
:D
After the Noto CJK finally landed in the Standard layer, Boldness issue became a major problem for them.
Investigation by ` vholten` proved it was caused by the old FreeType version (2.6.1) in the rendering server, but it seems there is no easy or safe way to fix the issue.
- Converting to (Cubic) OTF to (Quadratic) TTF will take very long time and the result may not be loseless.
- Upgrade newer FreeType via third-party PPA, or patch and build old FreeType from
apt-get source
will work, but dangerous and will become a maintenance hell.
Maybe we should give up on fixing it until we can get newer Linux distro?
