Originally created by @kumarharsh on GitHub (Jun 25, 2019).

Environment

Windows build number: [run "ver" at a command prompt]: 10.0.18362.175
Windows Terminal version (if applicable): 0.2.1715.0

Any other software?

Steps to reproduce

I'm running tmux in wsl. When I open vscode in any pane by writing code . or code-insiders ., the whole tmux display gets mutilated. Starting typing something in one pane starts changing other side panes.

Expected behavior

Launching code from the wsl command line shouldn't break tmux.

Actual behavior

The panes get broken - maybe it's a conpty bug, because I also get similar issues when running Alacritty using conpty. I can also intermittently see the cursor jumping between different panes for a brief moment (100ms or so)...

It's a conpty issue IMO. Here is a video capture of the issue: https://youtu.be/rN474X85Fgo

Does this reproduce outside of Windows Terminal?

Yes, with Alacritty - that's why I wrote this might be a conpty thing
