Editor Agent panel cannot start conversations on Linux (Agent Manager works)

Google Antigravity

Environment:

  • OS: Ubuntu 24.04 LTS

  • Antigravity version: 1.107.0

  • Flutter project (large codebase ~59 screens)

Issue:
The AI agent works correctly inside the “Open Agent Manager” window, but the embedded Editor Agent panel does not work.

Steps to reproduce:

  1. Open Antigravity

  2. Open a Flutter workspace

  3. Open the Agent panel in the editor

  4. Try to start a new conversation or run a command like “flutter analyze”

Expected behavior:
The agent should start a conversation and process the request.

Actual behavior:

  • The Agent panel flickers briefly

  • The “+” new conversation button is disabled or unresponsive

  • Sometimes the message “Failed to send” appears

  • AI works only inside the “Open Agent Manager” window

Additional notes:
This seems related to the embedded agent panel on Linux (possibly a webview/runtime issue). The same AI models work correctly in Agent Manager.

Same thing happens to me, except it’s for every workflow.
