“show agents side bar” button opens a useless area and cannot be closed

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Once clicking on the “show agents side bar” button, a blank functionless area will be expanded in agent pane/secondary side bar, occupying a wide space, and there’s no button or option to close it again.

For now, the only known solution is to reinstall Cursor again.

Steps to Reproduce

Click that “show agents side bar” button

Expected Behavior

If they are really useless, this button and this pane should be removed. Otherwise, we should be able to close this blank area.

Does this stop you from using Cursor

No - Cursor works, but with this issue

The second screenshot

You don’t need to reinstall. That panel is the agents sidebar, and there are a few ways to close it:

  1. Keyboard shortcut: Press Ctrl+Alt+U to toggle the sidebar off

  2. Command Palette: Press Ctrl+Shift+P, type “Toggle Agents Side Bar”, and run the command

  3. Inside the sidebar itself: There should be a small toggle button in the sidebar’s own header area

The original button you clicked disappears once the sidebar is open, which is why it looks like there’s no way to close it.

Hi, thanks for your reply.

The solution 1 works.

For solution 2, there’s not such command in Ctrl+Shift+P

And for solution 3, as the screenshot shows, it’s completely blank, no toggle button or anything.
This is definitely a bug.

Thanks
