@hellyguo Could you provide more details on which Linux distribution, input method, and fcitx version you're using?

I just tested this on Ubuntu 24.10. For Chinese I'm using Intelligent Pinyin and for Japanese I'm using Mozc. Everything worked under Ibus but when I switched to fcitx 4 both my Chinese and Japanese input methods stopped working for all apps, not just JavaFX. This makes me think that I'm not setting up fcitx correctly. I did reboot at each step as I changed the configuration.
