As I have said https://bugs.kde.org/show_bug.cgi?id=417570 in KDE Neon, after last plasma update, LO layout is without menu, and a general graphical "madness". I remove libreoffice-gtk so that I can use autokey, and without gtk (any version, both 2 or 3) LiO layout is absolutely unusable.
Any idea?

Today I found a workaround: let LO gtk, but updating autokey from github (from 0.90 to 095) and settings my abbreviations as insertable not from keyboard but from clipboard (as suggested here: https://github.com/autokey/autokey/issues/320). So now I have both a) a accettable LO grafical interface and b) autokey working.
