Comment # 1 on bug 1217920 from Xu Zhao

I have made some progress debugging this issue.

According to the fcitx5 on wayland best practice, on KDE Plasma it requires to
set the Virtual Keyboard to "fcitx5" in the KDE system settings. This will also
make KDE to autostart fcitx5 by default upon start.

However, this will conflict with /etc/xdg/autostart/org.fcitx.Fcitx5.desktop
and /usr/lib/systemd/user/fcitx5.service in the fcitx5 rpm package, making them
autostart to fail, because fcitx5 is already started by KDE.


Second, the best practice says QT_IM_MODULE and GTK_IM_MODULE are deprecated
and should not be set. However, in /usr/etc/X11/xim.d, the fcitx5 package
installs a bunch of files setting up these environment variables. They should
not be set if KDE plasma+Wayland is being used.
