Bug: Cursor position desync in chat editor - text insertion occurs at wrong location

[user531 (홍익)]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Bug Description:
The chat editor experiences multiple intermittent issues that significantly impact usability:

1. Cursor position desynchronization - text insertion occurs at wrong location
2. Input freezing - typing and paste operations become unresponsive

Issue 1: Cursor Position Desync
Steps to Reproduce:

1. Type: “hello. my name is cursor.”
2. Position cursor after “hello.” (between “hello.” and “my”)
3. Press Shift+Enter or paste content
4. Expected: Action occurs at cursor position
5. Actual: Action occurs at end of text (“cursor.”) instead

Issue 2: Input Freezing
Symptoms:

• Typing becomes completely unresponsive
• Paste operations (Ctrl+V) don’t work
• Chat input appears frozen
• No visual feedback when attempting to type

Common Characteristics:

• Both issues occur intermittently during extended usage
• Problems resolve after restarting Cursor
• Issues reoccur after continued use
• Significantly impacts workflow and productivity

Environment:

• Frequency: Intermittent but recurring

Workaround:
Restarting Cursor temporarily resolves both issues, but this disrupts workflow during longer coding sessions.

Impact:
These issues make the chat editor unreliable for extended development work, requiring frequent restarts to maintain functionality.

Steps to Reproduce

I don’t know.

No - Cursor works, but with this issue
