Electron font rendering looks blurry in W10

[Mispille]

On the left is Logseq windows desktop and the right is logseq in web browser

Looks blurry but I think it might just be stuck in grayscale anti-aliasing where the rest is in RGB subpixel mode as stated on a lot of github issues about this with Electron apps

Expected behavior
Working subpixel mode to render crisp text and be easy to read

Failed workarounds

• --disable-gpu in cmd line
• -webkit-font-smoothing in css with different options
• text-rendering: optimizeLegibility and other parameters
• Change options GPU Nvidia
• Cleartype (doesn't impact Electron rendering anyway)
• Replaced Inter font by "Inter Hinted for Windows" in %appdata%
• Trying other fonts
• Logseq in Chromium based browsers
• Logseq in Firefox

Firefox is the only way of having proper font rendering, but unable to use because of API needed to access local files

2 Potentially working solutions

1) Electron issue

It appears there is an Electron "issue" or "feature" that is known and affects other software like VSCode, I can confirm it is the same on this windows workstation

Sub-pixel anti-aliasing needs a non-transparent background of the layer containing the font glyphs

The solution as stated on there website is to implement

const { BrowserWindow } = require('electron')
const win = new BrowserWindow({
  backgroundColor: '#fff'
})

I could not test it as I don't know how to

2) Chromium issue

It could be an issue with DirectWrite specific to Windows
I could not test it as I don't know how to

Note

It is really subtle, but bad enough that it is hard to read sometimes and make me wonder if I had an issue with my screen

I can give feedback on pre-release if needed

Thx for your post.
I can tolerate the font rendering in win10 either, and want to find a way to change the font. Then I found you have tried and failed.

Is this the same issue?

(scrolling the left side makes the right one go blurry)
