1. open a html file in chrome

3. see the font bold difference

Expected behavior
they should be the same

Screenshots
above is neovide, below is chrome, you can see neovide is thiner

I tested in intellij idea and vscode and found intellij render font silimlar to neovide(thiner) and vscode is similar to chrome(bolder), maybe not an issue just different rendering method
Desktop (please complete the following information):

• OS: macos 14.2

I want to know is it possible to make font looks like chrome:)

We usually get reports that the fonts are too bold, so in that sense this bug report is strange.

But I can repeat this on Linux as well, and the different alias options does not fix it. It's a bit puzzling, since we use Skia for font rendering, the same library as Chrome uses, so it should look the same.

So, it's most likely a gamma issue, but I'm not sure what we need to do to fix, maybe switch to srgb rendering. This is most likely related:
https://skia.org/docs/dev/design/raster_tragedy/, and the document linked from it https://blog.johnnovak.net/2016/09/21/what-every-coder-should-know-about-gamma/

I also found neovide font weight 500(jb mono) is almost identical to kitty font weight 400 in light background, they mention gamma in text-composition document too. And kitty can specify a number to adjust that gamma.

What's the roles of skia_safe::Font and swash used as paird? Who decide the final looks?

This should allow it to be configured the same:

• feat: Configurable contrast and gamma #2510

Set gamma to 1.5 is nearly the same as chrome and vscode, it is great that I can adjust thickness for what I like!

The gamma and contrast options in Neovide 0.13.0 allows for all kinds of adjustments. https://neovide.dev/configuration.html#text-gamma-and-contrast
