Description

This has been happening for quite a while, and I bet there's a pretty simple explanation.

It might happen when you activate the Hyper-V vmconnect window.

Admittedly, I can't reproduce it on the Windows Evaluation VM with 1.17 to grab a screenshot, but it has happened to me enough times that I know it's lurking in there.

  1. Start a VM running Windows 11+
  2. Connect to it in Virtual Machine Connection, rejecting the enhanced session prompt
  3. Launch Terminal
  4. Focus on something other than the VMC window.
  5. Click on the Terminal window within the VMC window.
  6. Observe ;1_ is typed.

Contributor guide

Research direction
Investigate focus event handling in Terminal when it receives focus via Hyper V basic session. Look for spurious input generated by focus sequences (e.g., \e[?1004h) being misinterpreted as typed characters.
