Графические ошибки для границ окон, кнопок после обновления 2017-03-06, 16.04 [дубликат]

Вчера я добавил Sane PPA (драйверы сканера), обновление aptitude + обновление, а затем перезагрузка, когда меня попросили. Перезагрузка не завершилась (она просто оставалась на экране с «Ubuntu» и красными / белыми точками в течение 15 минут), поэтому я выключил и выключил машину.

Теперь я вижу то, что выглядит как неинициализированная видеопамять, где должны быть тени окон и угловые кнопки:

Я использую Dell XPS 15 "с NVidia 960M, работаю с графическими драйверами PPA (nvidia-375 375.39-0ubuntu0 ~ gpu16.04.2), в остальном довольно стоковая версия 16.04 с точки зрения пакетов.

Я могу откопать журналы того, какие именно пакеты были обновлены при вчерашнем обновлении aptitude, если это актуально.

Мои вопросы:

• Это известная проблема?
• Есть обходной путь или исправление?
• Если нет, то где лучше всего сообщить об ошибке?

Отредактируйте, чтобы добавить запрошенную информацию:
