Somehow this is the first time I see anyone else bring this up, but the fonts are absolutely displayed with wrong kerning on my mac, for my font (at 12pt) I was able to make it look the same as iTerm2 with adjust-cell-{width,height} both set to -5%.

I had an issue where Ghostty failed to render the text "th", so I think Ghostty just generally has a lot of font issues. Gave up trying to use it within minutes.

I noticed the colors looked off when I was trying out Ghostty as well. Adding this line to my config fixed it after restarting the app: `window-colorspace = display-p3`

Ghostty supports iTerm themes, so you should be able to transfer your preferred look-and-feel directly. I just picked one I liked, so I'm not familiar with the process, but it can be done.

Could you please point to the docs about how to transfer iTerm2 themes to Ghostty? I couldn't find it.

It looks like the process is more manual than I thought, sorry. There's something which imports themes from the iTerm2 color schemes website weekly, but from what I can find that isn't a feature which ships with Ghostty itself.

Here's the relevant docs page, which I hope explains why I mistakenly thought that transferring a theme directly from iTerm to Ghostty was possible. You could upload your theme to the website they're being sourced from, and wait a week. But that's clearly not the same thing.

I used font-thicken = true and it looks pretty good, very similar to iTerm.

It seems that I had iTerm2 configured to display bold text as bright text (instead of bold). And I use bold, coloured text in my prompt, so that threw me.

I configured

    bold-is-bright = true

and suddenly everything looks fine. I'll see how I get on with it.
