Occasionally, pasting doesn’t work in the chat window. Restarting Cursor doesn’t help, but it works if I open a new chat. I noticed that when this happens, the toolbar is missing from the chat window.
Hey, thanks for the report. The missing toolbar in the screenshot isn’t expected behavior.
Since it happens intermittently, could you help us figure out what might trigger it?
When it occurs, please check:
Does it happen in a specific workspace/project, or across all projects?
Any pattern related to chat length, file types being discussed, or actions before the toolbar disappears?
Does it affect both Agent mode Cmd+I and Ask mode Cmd+L, or just one?
Check the DevTools console for any errors
Potential workarounds:
Check if any macOS accessibility tools or clipboard managers might be interfering
The fact that a new chat fixes it suggests the chat UI is getting into a corrupted state. If you can spot any patterns, that’ll really help us find the root cause.
I was not able to repeat this bug so far. It happened 3 or 4 times. I can’t tell what trigger that. Maybe I tried some combination of Fix in chat for Typescript error and/or copy-paste from linter or typescript error window.
To open DevTools in Cursor, press Cmd+Shift+P and search for “Developer: Toggle Developer Tools”.
Since the bug is hard to reproduce, here’s what will help us track it down when it happens again:
Keep DevTools open while working (especially when using “Fix in chat” with TypeScript errors)
When the toolbar disappears, immediately check the Console tab in DevTools for any red errors, take a screenshot
Note whether it was Agent mode or Ask mode, and what you were doing right before (e.g., “Fix in chat” from a TypeScript error)
Your suspicion about the TypeScript error workflow is a great lead. If you can capture console errors next time it happens, it will really help engineering find the cause.
