Originally created by @rsynnest on GitHub (Jul 30, 2020).

Environment

Windows build number: 10.0.19041.0
Windows Terminal version: 1.2.2022.0 (Preview Build)
WSL2 Debian or Ubuntu

Steps to reproduce

  1. Open a Debian or Ubuntu WSL2 instance in a Windows Terminal
  2. Open vim and it will sometimes open in REPLACE mode. This happens seemingly at random, so you may need to quit and reopen vim a few times until you see the --REPLACE-- on the bottom left.
  3. I've reproduced the same behavior over SSH on various systems running different versions and flavors of Linux with various vanilla or custom .vimrc files. This behavior is not reproducible in other terminal emulators (specifically MobaXterm). This behavior also does not appear to affect Neovim in Windows Terminal.

Expected behavior

vim opens in Normal mode every time.

Actual behavior

vim randomly opens in Replace mode sometimes.

Thanks for the report! This is https://github.com/microsoft/terminal/issues/1637, which is marked an external tracking bug for win32-openssh. Unfortunately, the SSH client shipped with Windows is emitting an unusual or unexpected sequence in reply to Vim. More info at https://github.com/microsoft/terminal/issues/1637#issuecomment-663865934.
