Menu widget rendered in greyscale

Version: 1.35.1 (user setup) Commit: c7d83e57cd18f18026a8162d042843bda1bcf21f Date: 2019-06-12T14:30:02.622Z Electron: 3.1.8 Chrome: 66.0.3359.181 Node.js: 10.2.0 V8: 6.6.346.32 OS: Windows_NT x64 10.0.18362

I also double checked that the problem is on the Insider's Build.

Steps to Reproduce:

1. Observe text on screen. It should have gray subpixel rendering.
2. Open menu bar.
3. Observe text on screen. It should have RGB subpixel rendering.

This issue occurs on all text (except the menu bar submenus). I noticed it, because the text rendering looks better, but only when the menu bar was open! I would prefer all of it to use RGB subpixel rendering, like my other applications.

Does this issue occur when all extensions are disabled?: Yes
