:check_box_with_check: Cursor IDE

Describe the Bug

Korean input fails in the Agent chat panel when the input field is completely empty. The first Korean character cannot be input, or the IME composition window does not appear at all.

Steps to Reproduce

  1. Open Cursor Agent chat panel

  2. Ensure the input field is completely empty (no text at all)

  3. Switch to Korean input mode (Hangul) using IBus

  4. Try typing Korean characters

Expected Behavior

Korean characters should be composed and input normally from the first keystroke, just like in other applications (browser, text editor, terminal).

OS: Linux x64 6.17.0-14-generic
IME: IBus (default Ubuntu input method)

Workaround: Typing an English space or character first, then switching to Korean input works. However, this occurs every time when starting with Korean in an empty field.

Does this stop you from using Cursor?

(The workaround of typing English first makes it usable, but it’s annoying and disrupts workflow when starting conversations in Korean)
