Enable RGB font aliasing

[mad-wnn]

Hello,
I'm on Linux, running Birdwhale 4.2.1 and 4.2.2

I've noticed perceptual font render quality is lower than in my other apps, specificaly subpixel rendering is enforced to grayscale regardless my system settings that state RGB subpixel rendering should be used. That results in blurriness of a font.

Did a quick look up: per https://www.electronjs.org/docs/faq#the-font-looks-blurry-what-is-this-and-what-can-i-do an entry backgroundColor: '#fff' has been recommended to be passed to window constructor for blurriness to eventualy disappear.
Per above reference I did that change and that improved font rendering situation for my platform:

(result on the left, old behaviour on the right)

Could that change be incorporated into codebase?

Did you just add the code below? Does that alone improve it?

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

Yes, inserted the backgroundColor: '#fff' line into

whalebird-desktop/src/main/index.ts

Lines 270 to 273 in 0379891

	const mainOpts: BrowserWindowConstructorOptions = {
	titleBarStyle: 'hidden',
	x: mainWindowState.x,
	y: mainWindowState.y,

.. for the resulting:

  const mainOpts: BrowserWindowConstructorOptions = {
    backgroundColor: '#fff',
    titleBarStyle: 'hidden',
    x: mainWindowState.x,
    y: mainWindowState.y,
(...)

... did the job.
Sorry for lack of PR.
