Nope. This issue only appears in the GUI environment.

To help localize the problem, does this happen if you start Octave without the GUI?

This issue appears right after starting typing CJK characters with IBus in the command window. Copy-pasting CJK characters does not trigger the bug.

Steps to Reproduce

1. Install IBus and one of the CJK input methods, ex. Anthy
2. Execute "octave --gui"
3. Select Anthy input method and switch to Hiragana mode
4. Type some random hiragana in the command window

Actual Result

On my machine, CPU usage of octave-gui goes from 0% to 10% when idling. The CPU usage keeps around 10% until quitting Octave.

Expected Result

Typing CJK characters in GUI command window does not raise CPU usage permanently.
