Estranhas listras coloridas ao redor do windows - Ubuntu 16.04 [duplicate]

Question

Recentemente, notei que, ao redor das janelas, e no menu de clique direito de todos os aplicativos, há essas listras coloridas estranhas. Eles desaparecem depois que eu reinicio o Ubuntu ou o Unity, mas depois aparecem novamente pouco depois.

Listras coloridas ao redor das janelas dos terminais

Meu notebook usava a NVIDIA GeForce 960M e, para quem sabe, iniciei a programação CUDA há algumas semanas.

Estes são os pacotes instalados relacionados à nvidia:

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

O culpado é de fato a nova versão do driver NVidia. Revertendo para 375 não funciona porque IMHO também foi atualizado (versão menor) e / ou suas dependências são uma mistura de várias versões. De qualquer forma:

1. Remova o PPA. No meu computador eu deletei o arquivo /etc/apt/sources.list.d/graphics-drivers-ubuntu-ppa-xenial.list apontando para o repositório deb http://ppa.launchpad.net/graphics-drivers/ppa/ubuntu xenial main
2. Remove todos os pacotes NVidia instalados, por exemplo, nvidia-* . No meu computador eu deletei vários pacotes com apt remove nvidia-361 nvidia-375 nvidia-378
3. Atualize a lista de pacotes com apt update
4. Instale a última versão oficial (por exemplo, 367) com apt install nvidia-367

Como nota de rodapé, estou sempre impressionado com a forma como as atualizações regularmente quebram o Ubuntu ...
