Noto Sans font kerning issues
 
2 Attachment(s)
Hi all,

I'm (happily :)) using Slackware64 current, and realized that in chromium (and other chromium browsers), the kerning of the Noto sans family of fonts is off. This is especially noticeable because of the new Gmail design, the NYTimes front page, the new reddit, and the location bar of the Brave browser.

I attached a couple screenshots to demonstrate the effect.

My guess is that a suitable fontconfig profile is missing for this family of fonts. Does anyone have a potential solution?

Thanks!

There is a Slackbuild to install Noto Fonts on Slackware.

I don't think installing the Noto fonts locally will would solve the problem: indeed, I just installed the Slackbuild and the font rendering remains the same.

Okay I managed to fix the problem -- turns out that I need the symlink the right fontconfig configuration files. The key is to have "10-hinting-slight", "10-sub-pixel-rgb", and "11-lcdfilter-default". For future reference, here is what mine looks like:

Code:
/etc/fonts/conf.d $ ls -l
