[Windows] Mouse wheel scroll captured by input box instead of conversation history (regression)

[chenxizhang]

Describe the bug

Mouse wheel scrolling stopped working for navigating conversation history on Windows. Instead of scrolling through the chat history, the scroll event is captured by the text input box at the bottom of the screen, making it impossible to review previous conversation turns using the mouse.

This is a regression — scrolling worked correctly yesterday (March 9, 2026). The issue appeared today, likely after an update.

Keyboard workaround exists: PageUp / PageDown keys can still navigate conversation history correctly. Only mouse wheel scrolling is broken.

Related Issues

• Mouse scroll now scrolls chat history instead of output panel #1678 — Similar scroll behavior issue on macOS (mouse scrolls output panel vs history)
• Scrolling does not work with Tmux #1842 — Scroll issue in Tmux

This issue is distinct: on Windows, the mouse scroll is entirely consumed by the input text box rather than the conversation viewport.

Affected version

GitHub Copilot CLI 1.0.3 (Windows)

Steps to reproduce the behavior

1. Start Copilot CLI on Windows (copilot command)
2. Have a conversation with multiple turns (especially with long responses containing tables/code)
3. Try to scroll up with the mouse wheel to review earlier conversation history
4. Observed: Mouse wheel scrolls inside the text input box at the bottom, not the conversation area
5. Expected: Mouse wheel should scroll through conversation history

Expected behavior

Mouse wheel scrolling should navigate the conversation history (previous turns and responses), the same behavior as it had prior to the latest update.

Additional context

• OS: Windows 11
• Terminal: Windows Terminal
• Workaround: Use PageUp / PageDown keys to navigate history
• Regression: This worked correctly on March 9, 2026. Broke on March 10, 2026.

Adding a +1 to this issue. I've also found that to copy text I now need to press SHIFT when selecting. Both issues started a couple days ago.
