@lifeiscontent Thanks for reporting this! For step #2, did you manually share the ports, or did you just run “npm start” (and the ports were automatically shared)? I just want to make sure we have the right repro steps.

Also, when you say that your code was getting screwed up, do you mean that edits were being applied that neither participant was actually making?

@lostintangent it was manual I didn't realize that you could do it automatically.

Yep, we automatically discover servers (based on a list of well known ports) that are started from the integrated terminal. So if you run “npm start” from the VS Code terminal, we’d automatically share the port of the server it starts up.

That said, I’d love to understand more about the issue you noticed. I just tried reproing this and didn’t notice any issues with the cursor or code getting out of sync. Out of curiosity: do you recall if you renamed a file before the issues in step #4 occurred?

@lostintangent I'll follow back up with a video once I start pairing again.

@lostintangent I figured it out, it has to due with bad internet connections, when there is heavy latency VSCode I'm guessing is trying to send actions and when one of the participants is typing while VSCode tries to catch up, it gets out of sync.
