A resposta no meu caso foi excluir o .desktop
arquivo. Foi na localização global. Acho que devo ter lançado o PHPStorm como root em algum momento. O comando foi
sudo rm /usr/share/applications/jetbrains-phpstorm.desktop
Em seguida, relancei o phpstorm, tranquei o ícone, fechei e reiniciei via lançador.
$ cat ~ / .local / share / applications / jetbrains-phpstorm.desktop
