Comment # 4 on bug 1217920 from ulfbart

After update to plasma 6.0.1/6.0.2 message was shown:

"Fcitx should be launched by KWin under KDE Wayland in order to use Wayland
input method frontend. This can improve the experience when using Fcitx on
Wayland. To configure this, you need to go to "System Settings" -> "Virtual
keyboard" and select "Fcitx 5" from it. You may also need to disable tools that
launches input method, such as imsettings on Fedora, or im-config on
Debian/Ubuntu. For more details see
