Soome UI elements of KDE Plasma doesn't accept Asian Input(via IBUS). I tried every solution on the Archwiki. Is there anything else I can do?

Desktops & Window Managers Kde Plasma
,
#1

This is a fresh Minimal install of Manjaro KDE.
I installed ibus and ibus-hangul using Manjaro Hello applications.
Then, I did all the tweaks in the Arch wiki under the ibus KDE tab

Added

export GTK_IM_MODULE=ibus
export XMODIFIERS=@im=ibus
export QT_IM_MODULE=ibus

To .bashrc
Added

export QT_IM_MODULE=ibus

to .xprofile

Added

export OOO_FORCE_DESKTOP="gnome"

to .xprofile
Then finally added

 export GTK_IM_MODULE=ibus
 export XMODIFIERS=@im=ibus
 export QT_IM_MODULE=ibus

to .xintrc

but to no effect.

The issue can be seen here

Any help with this would be appreciated.

P.S, would using FCITX be better?
