Графической проблеме о Kubuntu, plasmashell не удалось запуститься

Я использую Kubuntu. Я заметил что-то странное. KDE Plasma, который, оказалось, устанавливал обновления, но когда я запустил систему, я получил некоторые черные и белые эффекты, пропустив пункты меню, и т.д.

Я сделал это видео YouTube для показа то, что я имею в виду.

Все работает хорошо (эффекты значков, максимизируйте и т.д.), но у меня нет Рабочего стола, и я не могу щелкнуть правой кнопкой по рабочему столу.

Я попробовал

• переустанавливая целую kde плазму (который включает kubuntu +kde плазма, я использующий эту установку на восстановлении),
• попробованный для удаления полностью завершенный и проверил, что файлы здесь или нет.
• попробованный для изменения kscreen (папка включая conf)
