I don't notice any typing latency on Slack and I'm usually pretty sensitive to it. That said, Atom with a bunch of plugins can chug a little.

I don't notice any notable latency in discord, vscode, etc

But I do notice latency in hyper.js, and it just makes it feel very "dull", and that's what I think a lot of people know of electron terminals

plus the competition from native apps is a bit absurd in terms of performance, with most of the serious ones either rendering asap or on the next frame (when vsync'd)

and why would your experience of one terminal app based on Electron apply to all other terminal apps based on Electron? You even say that you don't notice latency in VSCode. A text editor and a terminal have similar problems to solve.

Never said it applied to all electron terminals

I would of tested this one, but no windows build, and I'm not using a linux install atm

editors don't roundtrip to a separate application through multiple buffers (bash, zsh, fish, or whatever) to decide if they need to show a color or letter or nothing
