i switched from alacritty -> ghostty, and occasionally use zed.
i can't recall why i made the transition (maybe just to try it out, and it became default?). i can't think of any practical consequences of this transition.
why do you care about whether zed uses alacritty or ghostty under the hood?
Kitty Graphics Protocol support and subtle font rendering differences between Ghostty and Alacritty that drive me nuts.
I have reported font rendering issues to Alacritty in the past and let's just say the developer was not exactly receptive to fixing them since they occur on macOS and not his preferred OS of Linux.
