IDE freezes when window not active

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Cursor freezes everytime an agent finishes with a prompt (or when the agent halts and awaits user input) and the IDE is not the active window.

It only freezes when Cursor is not the active window. So when the agent is executing a prompt, and I click on my Chrome window to see what the agent has created so far, if the agent finishes while the IDE is not the active window, it will completely freeze and be ENTIRELY unresponsive. This ALWAYS happens without fail.

I am using Cursor on Windows, and it happens when Cursor is using a standard Windows instance, and also when I am connected to WSL. It always freezes.

Steps to Reproduce

Have agent answer prompt, while it is answering the prompt click outside the window.

Expected Behavior

It should not freeze.

Operating System

Windows 10/11

For AI issues: which model did you use?

I used Auto mode for the agent.

Hey, thanks for the report. This is a known issue on Windows. It’s related to system notifications that Cursor sends when the agent finishes a task and the app window isn’t in focus.

Try this workaround: go to Settings > General > Notifications and turn off System Notifications. This helped other users with the same issue:

If disabling notifications doesn’t help, also try:

  1. Run Cursor without extensions: cursor --disable-extensions
  2. Restart your system. In one similar case, a full Windows restart fixed it

Let me know if it helped.
