additional information:
Seems that IM module (like /usr/lib64/gtk-3.0/3.0.0/immodules/im-fcitx5.so or /usr/lib64/gtk-3.0/3.0.0/immodules/im-ibus.so) isn't loaded at all, when using Wayland.

Still present in #120034 (comment)
Maybe waiting a newer electron 12.x release?

It may get support in electron 14 ( chromium 93 ) or later. electron 12 ( chromium 89 ) or electron 13 ( chromium 91 ) don't support it.

ibus not working at all under wayland because not support the latest version of the protocol.

Does Electron or Chromium currently supports text_input_unstable_v3 or text_input_unstable_v1 protocol?

It support text_input_unstable_v1: https://github.com/chromium/chromium/blob/master/ui/ozone/platform/wayland/host/zwp_text_input_wrapper_v1.h

Basically, current Wayland protocols not enough for normal IME but developers working on it - https://gitlab.freedesktop.org/wayland/wayland-protocols/-/issues/39

[microcai]

using gtk-4 will solve it. but how to use gtk-4 ? chrome has command flag for it.

[deepak1556]

gtk-4 is not supported in electron yet, so the command line flag cannot be used.

Is this issue present with latest insiders https://code.visualstudio.com/insiders which comes with newer runtime version ?

[karuboniru]

This problem still exist with code-1.67.1-1651841920 and code-insiders-1.68.0-1652420254 version. Chromium's input method support can be enabled by --gtk-version=4, while this is not possible since follow error will be generated when running code --enable-features=UseOzonePlatform --ozone-platform=wayland --gtk-version=4 --verbose
