Originally created by @jeapostrophe on GitHub (Apr 6, 2021).

Windows Terminal version (or Windows build number)

Windows Terminal Preview Version: 1.7.572.0

Other Software

NVIM v0.4.4
Pengwin WSL

Steps to reproduce

The problem happens when I have vertical splits and modify one on the right. I have attached a video. But this also reproduces for me:

$ seq 800 > /tmp/a.py
$ seq 800 > /tmp/b.c
$ nvim /tmp/a.py
:vsp /tmp/b.c
# Select right frame
# Navigate to right of 9
i
# Press enter and it looks really messed up... the LHS is being modified and the RHS is wrong

Expected Behavior

It should show the same file contents with no problems

Actual Behavior

This error may depend on syntax coloring being turned on and other similar things that are enabled in my setup

Just to be sure, does this repro in neovim without any custom config enabled at all? (something like nvim --clean might work)

I does not without any custom config. I intend to record the sequence of terminal commands and submitting that
