Originally created by @JanDeDobbeleer on GitHub (May 27, 2023).

Windows Terminal version

1.18.1421.0

Windows build number

10.0.22000.0

Other Software

Oh My Posh v16.9.0

Steps to reproduce

Oh My Posh recently added support for FTCS marks which seems to work really well with the latest preview release of Terminal, VSCode and iTerm. However, when typing clear, the entire prompt disappears and you can see the multiple cursors when typing (seems that way). Waiting a few seconds, or removing focus from Windows Terminal, it renders the prompt again. This behaviour wasn't there in 1.17.

This seems to be an issue with the new Atlas Engine as I can't reproduce it when it's not enabled.

EDIT: even without printing the marks, the behaviour is there.

Expected Behavior

It displays the prompt correctly.

Actual Behavior

There's an invisible prompt at the top (and consequent prompts as well for a few seconds).

@zadjii-msft i have the same problem and I'm using the following font CaskaydiaCove Nerd Font so in my case it should be fixed by #15403.

I see the issue. I also cannot capture a screenshot of the problem since that causes the problem to go away. And I'm also using CaskaydiaCove Nerd Font.

@rkeithhill-keysight true, I noticed the video I posted above also doesn't show the issue clearly and you can't screenshot either because I'm too slow 😂

Once again, I'm sorry for causing this issue! It was fixed by #15403 which has shipped in v1.18.1462.0. It should also already be available via the app store. I hope it works now!
