Japanese IME input auto-commits in Chat, Send button stops working

Bug Reports

:lady_beetle: Bug Description
When typing in Japanese in the Chat view, the input gets automatically committed before the user finishes converting it (e.g., pressing space to select kanji). This makes it impossible to enter a proper message, and the Send button becomes unresponsive after the forced commit.

:counterclockwise_arrows_button: Steps to Reproduce

  1. Open the Chat view.
  2. Start typing in Japanese using romaji (e.g., typing nihongonomojinyuuryoku for “日本語の文字入力”).
  3. The input gets automatically committed around “nihon…”, without allowing spacebar conversion.
  4. After that, the Send button no longer works.
  5. No error messages appear.

:laptop: Environment

  • OS: Windows 11
  • Cursor version: 0.47.8
  • VSCode engine: 1.92.2
  • IME: Google Japanese Input & Windows IME (both affected)

:prohibited: Impact
Yes, this bug prevents me from using Cursor to interact with the Agent in Japanese.
The only workaround is typing in another editor and pasting into Cursor, which is very inconvenient.

Update:
Weirdly, I can’t reproduce it anymore.
No update or environment change on my side, so not sure what fixed it.
Will follow up if it happens again.

Update:
Never mind, it’s back. Thought it was fixed, but the issue just happened again.
No updates or changes on my end.
