Windows Alpha: Terminal feels very slow and laggy

[DeveloperPaul123]

Summary

Overall, the terminal in Zed feels very slow and laggy, especially while typing.

Description

I'm currently using pswh.exe with a very custom profile but the same behavior can be seen with powershell and Git bash.

Steps to trigger the problem:

1. Open the terminal
2. Attempt to try many characters very quickly
3. Note the delay in characters showing up in the terminal.

Expected Behavior:

There should not be lag - behavior should be similar to system terminal emulators (WezTerm, Alacritty, Windows Terminal and so on).

Actual Behavior:

The terminal is quite slow. Below is a demonstration of me typing many characters very quickly and then waiting for the text to show up.
