I have Kde Neon, Muon does not display the menu bar as shown! if I open it with the sudo yes ... how can I normalize Muon's vision? do i need to delete a specific file? do i have to give a command from the terminal?
PS:: muon with the second user account you can see well, it must be a corrupt file in the home, could you tell me the exact file to delete? without touching all the folders like .cache, .config and. local

resolved abruptly! i deleted from the 3 named folders: kde,dolphin, maybe kwin (but i don't remember well) and flying files! now but i have to fix the look of kde!
