Typing `^` in a script makes the editor unusable

[notroid5]

Tested versions

• Reproducible in: 4.4.1.stable, 4.4.stable, 4.3.stable, 4.2.stable

System information

Godot v4.4.1.stable - Ubuntu 24.04.2 LTS 24.04 on Wayland - X11 display driver, Multi-window, 1 monitor - OpenGL 3 (Compatibility) - AMD Radeon 760M (radeonsi, gfx1103_r1, LLVM 19.1.1, DRM 3.57, 6.8.0-63-generic) - AMD Ryzen 5 7640U w/ Radeon 760M Graphics (12 threads)

Issue description

If you type ^ in a script, the keyboard no longer works in the whole editor (not just the script)
This is quite annoying since I happen to press it every now and then

Workaround:
Project > Reload Current Project
(or Project > Quit to Project List, or Scene > Quit)
Even if saved, the ^ will be gone

Tried searching for this issue but don't know how to force github to search ^ ...

Did not test earlier versions, will update after creating this issue
Updated tested versions
Note: In 4.2, the character ^ does not appear on screen after pressing the key. The issue is the same, though. Can't test 4.1 cause it keeps crashing when trying to create a new script right after loading a new project.

Steps to reproduce

• make a brand new project
• make a new script
• type ^
• keyboard is no longer working (within Godot)

Minimal reproduction project (MRP)

Closing this as duplicate of #85664
TL;DR: Downgrade or remove ibus

Also make sure to report this bug to Ubuntu. They have been shipping a broken ibus version in their LTS for like a year now. We can't fix this on our end.
