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.

@hellyguo I can't reproduce the problem you're seeing. I configured a Debian Bookworm system with Fcitx5 and Pinyin and tested this PR and everything worked. The Linux and Fcitx version numbers are the same as yours. I also installed fcitx5 on my existing Ubuntu 24.10 system and it worked there, also.

The behavior seems a little odd but it matches the behavior of other Linux apps (I see Roman letters inserted into the JavaFX TextField until I select Chinese text in the IM). In your screen capture the input method window was clearly in the wrong location but in my testing it was correctly positioned near the JavaFX caret.
