Hey, thanks for the report.
I can see the screenshot where the chat panels are duplicated. This is a known issue related to the new Agent sidebar. Please try this workaround:
- Go to Settings → Agents → Default Location, and set it to “Pane” instead of “Editor”
- Close the Agent panel
- Try creating a new chat again
This helped in similar cases: CMD+OPT+B often opens two chat sidebars
Let me know if the issue persists.
