Maybe I should open a new issue for this, but on my setup, typing in Gnome Files to start searching did not function as expected.
Using rime, the symbol of the first keystroke was invalidated, while with libhangul and anthy, the letters were written but was plainly written (e.g. ㄴㅣㅁ프、nインプ), and dragging a character being edited not only moved it around but also selected area from the character's spot to the drag point.

Hi, Thank you for your comment.

Pop!_OS 21.10 has a code that forces "IBUS" environment variables.
You can find "pop-default-settings" package. (/etc/profile.d/pop-im-ibus.sh)

There are two solutions.
nimf must be installed & "im-config -n nimf" setting.

First, Remove file or comment out content. (/etc/profile.d/pop-im-ibus.sh)

and just reboot 😄

Second, Add the nimf environment variable.
It is similar to the POP_OS 21.10.

export GTK_IM_MODULE=nimf
export QT_IM_MODULE=nimf
export XMODIFIERS=@im=nimf

You can write the .bashrc, .profile, /etc/profile ... etc.
or recycle the /etc/profile.d/pop-im-ibus.sh.

and just reboot 😄

It's not that nimf's not functioning on every application; just on the version of Chromium I'm using, afaict.
I tested a few apps I use regularly just now to see if it works on them.
What it works on:
Firefox, Zotero, Gnome apps (Files, Terminal, & Settings were checked), VSCode, Alacritty
Where it doesn't:
Gnome shell, Discord (flatpak), Ungoogled-Chromium (flatpak), Joplin (flatpak), Bitwarden client (flatpak)

...Now that I list them, I can see that it's probably just with flatpak that nimf doesn't work.

In the meanwhile, the solution provided does not work, as had been reported on flatpak repository. Solution provided here (in KO-KR) may work, but I haven’t tried.

Aldho this seems to be solvable on the flatpak/snap side, it is no lesser an issue since major browsers other than the ones preinstalled use such packaging systems.
