Welcome to the forum!
KDE is now using Wayland (rather than X11) as the graphics platform, and this seems to be a minor glitch in the transition.
IBus is used to switch between different keyboard layouts, so you may not experience any issues unless changing keyboard layout (language) under some circumstances.
The message seems to be outdated as of KDE 6.3.4. Try this:
https://github.com/ibus/ibus/issues/2753
System Settings (GUI) > Keyboard > Virtual Keyboard > IBus Wayland.
