I'm not doubting your personal experience, but I find the crashes you mentioned surprising; I have never once, since v1.0.1, had Ghostty crash. Tbf I use it with tmux, so I'm not exercising some of its capabilities. But with tmux, I have at any given time 5-7 sessions, each with 2-5 windows, some with panes.

Datapoint: I’m running nightly now because the latest 1.2 release has a known crash-on-wake bug when disconnecting an external monitor. Accordingly the issue tracker it was fixed months ago, but it’s not in a release. The nightly is stable though.

Didn’t realize how may projects use libghostty, will try cmux one of these days.
