Switching keyboard layouts ZOS 18 Core

Hi, people! Happy New Year!

Setting -> Keyboard -> Input source switching
Switch input sources individually earth windows

It doesn't work - the same font appears in all open windows.

I wasn't able to reproduce this error and tested it on Wayland and XOrg.
Do you have changed the default settings for keyboard shortcuts and created custom ones?

I tried this (alt-shift):
gsettings set org.gnome.desktop.wm.keybindings switch-input-source "['Alt_L']"
gsettings set org.gnome.desktop.wm.keybindings switch-input-source-backward "['Shift_L']"

But then I reset the keyboard settings.

ps: Now I installed ZOS under VirtualBox and VMWare - same thing, didn't change anything

Wayland, Language English and Russian (en-ru)

I installed ZOS 18 Core R2 on a clean drive on another computer. The keyboard layout issue persisted.

And what happens when you use the default keyboard shortcut to change input language Super+Space ? Shift_L and Alt_L can be problematic as standalone keys for shortcuts because they are also used in other combined shortcuts / functions.

On the newly installed system, only Super+Space
