Canvas DevTools panel has no close button

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The DevTools panel that opens against a Cursor canvas has no visible close affordance. The standard Chromium DevTools “×” button in the top-right of the panel — which normally dismisses DevTools — is missing. There is no apparent menu item, button, or keyboard shortcut that closes the panel either, leaving it permanently docked over half the canvas viewport once opened.

Steps to Reproduce

  1. Open a .canvas.tsx file in Cursor so the canvas renders in the right pane.
  2. Open DevTools on the canvas (e.g. right-click in the canvas pane → Inspect, or via the canvas’s DevTools shortcut).
  3. The DevTools panel opens docked to the canvas, occupying roughly half the pane width and showing the Elements / Console / Sources / Network / Performance / Memory tabs.
  4. Inspect the DevTools chrome for a close button.

Expected Behavior

DevTools should have a visible close affordance — typically an “×” in the top-right of the panel — that dismisses DevTools and restores the full canvas render, matching standard Chromium DevTools behavior. Re-pressing the shortcut that opened DevTools should also toggle it closed.

Additional Information

Current Workaround : Reload Cursor window

Does this stop you from using Cursor

No - Cursor works, but with this issue

This is a known bug with DevTools in embedded panels (canvases, browser views). The close button and some other DevTools UI elements aren’t rendering properly in the docked view.

A quicker workaround than reloading the window: press Cmd+Option+I (macOS) while the canvas panel is focused. That toggles DevTools open and closed, so you can dismiss it without reloading.

Our team is aware and working on a fix for the DevTools chrome UI in these embedded views.

Thank you for your reply.

I did try this, but it had no effect. I’ve also checked that no other keybindings are interfering with it. I tried it on my colleague’s laptop as well, and it didn’t work there either, which is why I’m currently refreshing it.

Thanks for confirming. I’ve filed a new bug report for this so that the relevant team can look into it. Will keep you updated on the fix.
