Странные цветные полосы вокруг окон - Ubuntu 16.04 [дубликат]

Недавно я заметил, что вокруг окон и в контекстном меню всех приложений есть эти странные цветные полосы. Они исчезают после перезапуска Ubuntu или Unity, но вскоре появляются снова.

В моем ноутбуке использовалась NVIDIA GeForce 960M, и для тех, кто знает, я только начал программировать на CUDA несколько недель назад.

Это установленные пакеты, относящиеся к nvidia:

quan@quantran:~$ sudo apt list --installed | grep nvidia
