Not correctly choosing fonts in Ubuntu 16.04 LTS

[renkun-ken]

• Electron version: 0.35.6
• Operating system: Ubuntu 16.04 LTS

I'm using the latest release of Slack (v2.0.3 64-bit), VSCode (v1.0.0), and GitKraken (v1.1.0) in Ubuntu. The font rendering are good in Ubuntu 15.10. But when I had a fresh install of the newly released Ubuntu 16.04 LTS, the monospace and Chinese font rendering of these apps becomes weird (too thin).

Firefox can correctly use Noto Sans CJK SC Regular to render Chinese font as it becomes default for Chinese language in Ubuntu 16.04 LTS. But Electron-based applications seem to suffer from not falling back to the right font in the GUI. Instead of choosing Noto Sans CJK SC Regular for Chinese characters, it seems to have chosen Noto Sans CJK SC Thin, which is too thin for reading.

My OS language and locales are English with Chinese installed (so I have the necessary fonts).

The following text is for test:

hello, world!
测试文字
文字如果太细了就看不清楚

In gedit, the font looks fine:

But in Electron-based apps, fonts are too thin:

This seems to be an upstream bug of Chromium: https://crbug.com/595690.

Here is a walk around: http://www.xiangji.me/2016/04/29/solving-cjk-font-rendering-issue-in-chrome-on-ubuntu-16.04/. I test it and it solves my problem :)

It looks like fonts-noto-cjk package is updated and the problem is gone.
