Does this still happen in Electron 4.0.0-beta.7?

这仍然发生在Electron 4.0.0-beta.7中吗？

Yes, the font display is different from Chrome.

[nornagon]

I'm also seeing differences in font rendering between Chrome 70 and Electron 4.0.0-beta.7 around subpixel antialiasing. I'm not seeing the "bold" artifacts that you are though.

These are both rendering with PingFang SC.

Looks like subpixel antialiasing is working fine in Electron 2.0.13, but not in 3.0.x or 4.0.0.

(see thread for an experiment to try around subpixel rendering--I was able to use the workaround to get subPixel rendering with 3.0.7)

chrome 70
vs
2.0.13

See also #15486. Not related to subpixel anti-aliasing, but could explain some other font choice differences.
