Config options different from defaults:

[page-down]

It works fine under X11.
I tried the previous kitty versions and could not get ibus to work under wayland. (Arch Linux + KDE)

GLFW_IM_MODULE=ibus kitty

Did I miss something?

[kovidgoyal]

Wayland has its own text input protocol, via the compositor so
GLFW_IM_MODULE is not needed.

OK, I installed fcitx5 and it works as expected.
No additional configuration is required, it works out of the box.

fcitx5 wayland im frontend -> kwin wayland -> zwp_text_input_v3 -> kitty

@mendaxcat
I don't know how to configure ibus related so I can't help you.

[page-down]

I confirmed that IME works fine with Debian 11 GNOME + Wayland + IBus.

Debian 11.2
IBus 1.5.23
kitty 0.24.4

XDG_SESSION_TYPE=wayland

Did you follow my steps to reproduce the problem?
The IME does work in kitty, but not after switching tab.

kitty under x11 does not have this problem. @page-down

... but not after switching tab ...

I noticed that after switching windows the IME needs to be switched again to work.
I also found a problem with leftover pre-edit text.
