Hey, thanks for the report. We’re seeing similar Agents tab freezes on macOS and Windows in recent versions. Please try:

Check settings.json:

  • Open Command Palette (CMD+Shift+P) → Preferences: Open User Settings (JSON)
  • Look for ”workbench.editor.showTabs": "single"
  • If present, change it to ”multiple" or remove the line

Test in Safe Mode:

  • Launch from terminal: cursor --disable-extensions to start without extensions
  • Switch to Agents mode: does it still freeze?

Also helpful:

  • Clear chat history if you have long conversations saved
  • Check Activity Monitor during the freeze: what’s the memory usage?
  • Does this happen across all projects or only some?
  • Does the same happen when switching to Agents with (CMD+E)?

Let me know what helps!

Yes, changing “workbench.editor.showTabs” to “multiple” fixed it :laughing:

Thank you
