I tried Ghostty for a few months, but found that it had the slowest launch time of all the terminals (NixOS) - we're talking seconds instead of tens of ms. Sadly, it looks like the launch improvements here are for macos.
I had a similar problem maybe a year back. I've stuck to Foot since. I've got a new laptop now though and might be worth giving Ghostty another spin.
What did you settle on?
I like foot but don't mind waiting a few tens of ms in exchange for kitty's graphics.
I've been working around it by setting my keybind to
to instantly open new terminal windows when ghostty is already running in a single instance.
