Description Mateus Rodrigues Costa 2023-11-24 22:17:16 UTC

ibus 1.5.29~rc2 breaks some applications with its new preedit text behavior.
Downgrading to ibus 1.5.29~rc1 solves it.

This issue happens when using the preedit functionality, for example when using the "Us-Intl with deadkeys" layout and trying to input accented characters (for example: á, é, ã).

The noticed behavior is:

On Android Studio: The application gets confused and, after preedit is used for the first time, all new characters get stuck on being inserted in the same place as the preedit until window is switched.

On Godot engine: After preedit tries to get used, Godot refuses to receive further text input



Reproducible: Always

Steps to Reproduce:
1. Have ibus 1.5.29~rc2 with a layout such as Us-Intl with deadkeys
2. Open Godot or any Java application
3. Try to type accented charaters
Actual Results:  
Wrong preedit behavior prevent proper usage of application.
Worst case scenario applicaiton stopped receiving text input.

Expected Results:  
Proper preedit functionality.

It would be a late report and you could report it in Fedora 39 beta.
Currently I'm evaluating Fedora 37 bugs and making a plan for Fedora 40.
I will evaluate your issue *after* other bugs are evaluated.
