Huh. That's the darndest thing - this doesn't repro for me on my 18.04 distro on WSL 1, but definitely does on my 20.04 running WSL 2. Sounds like it's definitely a WSL 2 issue. Let's move this to their repo.

Thanks @zadjii-msft for the quick response. Yes, WSL 1 works fine. I reported this issue here because I saw this statement when I was trying to raise an issue in WSL repo:

https://github.com/microsoft/WSL/issues/new?assignees=&labels=&template=bug_report.md&title=

If this is a console issue (a problem with layout, rendering, colors, etc.), please post the issue to the Terminal tracker: https://github.com/microsoft/terminal/issues

Yea, this is treading that blurry line. Considering this works fine in WSL1, I'm inclined to believe that it's a WSL2 issue. If they find out that it's actually on us, I'd be happy to reopen and fix it. Good thing their PM's office is just down the hall from us 😄

as if anyone's in offices anymore 😢

Nice! Let's stay tuned. I bumped into this issue while pasting multiple Azure CLI commands at the same time (e.g. to create a private DNS zone), becoming a "first-party victim". 🤣

Facing the same issue while using ssh to connect to an Azure VM (in all of Windows Terminal, Windows 10 built-in terminal and VS Code):

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.5 LTS
Release:        18.04
Codename:       bionic

When pasting these lines into the terminal:

sleep 2
sleep 2
sleep 2
