Describe the bug

This issue effectively makes Warp unusable in my environment.
I am very interested in using Warp, but I am unable to do so because the application freezes whenever I type Korean.

When typing Korean using kime IME in Warp terminal, the application freezes or becomes unresponsive.
English input works normally.
The issue occurs consistently when composing Hangul characters.
