Triple equal glyph renders incorrectly

[javigaralva]

This is, by far, my favourite code font. Thanks for make me happy when I'm coding. And this is the reason why I create this issue, to try to make it better :)

The tiple equal glyph doesn't render well in mono regular and mono italic. It seems like the three bars are not equidistant one each others.

This is a comparative image between Fatasque Sans Mono and Fire Code to ilustrate it:

Please, click on all the images to see all of them at 100% with no pixel interpolation.

The previous image is from Visual Studio Code, but ocurrs using https://fontlibrary.org/en/font/fantasque-sans-mono

It seems that depends on the zoom factor:

zoom factor 175% =>bad render

zoom factor 150% =>bad render

zoom factor 125% =>good render

zoom factor 110% =>bad render

zoom factor 100% =>bad render

zoom factor 90% =>bad render

zoom factor 80% => good render

I've tried different fonts with triple equal glyph and this issue doesn't ocurr.

Thank you :)
