I released the ibus-typing-booster-1.4.0 update now:
https://bodhi.fedoraproject.org/updates/FEDORA-2018-f948d3369a
but I just remembered that you use Gnome Wayland. Unfortunately under Wayland the preedit style is ignored. Wayland always draws the underline under the preedit, even if the input method requests to turn it off. So ibus-typing-booster does have this nice new option now but it doesn’t work under Wayland ☹. I think sometime in the future this will be fixed in Wayland though and then it will start working.
What is the best known setup to use this? I already have LXDE installed. Or should I switch to Gnome Xorg?
I don’t know really, it is a matter of preference. Personally I am using i3, but I think all of these are fine.
If you like Gnome, you could try Gnome Xorg.
Of course Wayland will be the future, and it is already the default, so this really should be fixed in Wayland.
