--- Comment #8 from Konrad Materka <mate...@gmail.com> --- I had to check :) It is not working on "pure" LXDE. LXDE has a QPA plugin, similar one as KDE has. Run your test application with: XDG_SESSION_DESKTOP=X QT_QPA_PLATFORMTHEME=X ./menubugtest You will see exactly the same results. You can also remove/move the file: /usr/lib/x86_64-linux-gnu/qt5/plugins/platformthemes/libqtlxqt.so On KDE install package "plasma-integration" (at least on *Ubuntu) at will work correctly, the same as in LXDE. It should be installed by default. -- You are receiving this mail because: You are watching all bug changes.
