The problem was with:
m_menu->setVisible(m_visible);
setters/getters should not have side effects or any logic, but this method
has. Detached menu stayed as top level window and rendered itself.
VLC has a bug, each systray menu update creates new QMenu, but old one is not
deleted:
https://github.com/videolan/vlc/blob/master/modules/gui/qt/menus.cpp#L655
QMenu::clear() deletes all attached actions (if not used somewhere else) but
not menus! It is weird, but someone explained it here:
