I was using Copilot Chat on GitHub Codespaces but couldn't see Copilot's responses in the chat window. Although the responses were not visible in the chat window, I was able to copy the response text. When I checked the logs with Show Chat Debug View, it looked like the response itself succeeded, but the response was not displayed in the chat window.

I can see the chat responses in my local VS Code, but I cannot see them in Codespaces.

It sounds like Copilot Chat is successfully generating responses in your Codespace, but the UI isn’t rendering them. This can happen if the Codespaces editor webview fails to refresh or if there’s a temporary rendering bug in the chat panel.

Things you can try:

1. Reload the Codespaces window (Ctrl+Shift+P → Reload Window).
2. Clear browser cache if you’re using Codespaces in the browser, then reopen the workspace.
3. Update your Codespaces VS Code version — sometimes older versions have chat panel rendering issues.
4. Disable conflicting extensions that might override or interfere with the chat panel UI.
5. Check View → Chat: Show Chat Debug View to confirm responses are arriving (which you’ve already done)

If responses are visible in the debug log but not in the panel after a reload/update, it’s likely a frontend rendering bug. In that case, please open an issue via GitHub Support with:

• A short reproduction video or screenshots
• Your Codespaces + VS Code version
• The Copilot extension version

This will help the team trace whether it’s a Codespaces UI issue or an extension rendering problem.

did you install in the Codespaces, the GitHub Copilot and the GitHub Copilot Chat ? in my case, though it's always present, I always install it to see the exact models, and I guess you installed it because I can see the models,

also, if you full rebuild the container, you need to install it again, I was getting errors if not

I found the cause of the chat responses not appearing: when chat.math.enable is set to true, it seems to affect the display.
