Voice / speech-to-text with mic causes Bluetooth mouse pointer to freeze until stopping recording (Ctrl+Shift+Space)

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Hello - WIndows 10 PC with latest version of Cursor. I have a bluetooth mouse/keyboard/headphones. When using cursor app with ‘new agent’, Ill use the voice input button, and speak and then it will convert that speech to text. About 50% of the time, the mouse gets locked up and will not move. The keyboard works, and I am forced to press CTRL + SHIFT + SPACE to end the speech to text recording. Afterwards, the mouse starts working again…other times the mouse does not have this problem. This happens very very frequently. Please fix or advise on how to avoid. E.G. I close my chrome browser and other applications but doesnt seem to matter.

Steps to Reproduce

Use the voice recorder/speech to text.

Expected Behavior

Mouse is not suppose to lock up/freeze.

Operating System

Windows 10/11

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the detailed report. This looks like a known limitation of the Windows Bluetooth stack, not a Cursor bug.

When you turn on voice input, Bluetooth headphones switch from the A2DP profile playback only to HSP or HFP with mic. That profile cuts bandwidth a lot, and the Bluetooth radio shares it with your mouse and keyboard, so the cursor starts freezing. The keyboard usually uses less traffic, so it keeps working. When recording stops, the profile switches back to A2DP and the mouse comes back. This is a common issue and not specific to Cursor. You can reproduce it in a browser too if you use the mic through Bluetooth headphones.

Workarounds:

  • Use a wired mouse or a mouse with a USB dongle not Bluetooth. This usually fixes it полностью
  • Use a wired or USB mic for voice input instead of Bluetooth headphones
  • Update your Bluetooth drivers, especially if you have Intel Wireless Bluetooth since there are known issues there
  • If you can, use a separate USB Bluetooth adapter for the mouse so the devices are on different radios

Let me know if the issue still happens after switching the mouse or mic to wired, and we can dig deeper.

Wow. Thank you for the thorough and detailed response. This makes sense and I’ll explore these options.
