Ugly vertical lines

After switching from the Nouveau driver I am seeing ugly vertical lines on window title and borders.

This use to be a problem with the Nouveau drive, but they fixed it a while back. Surprised it’s still an issue with NVidia drivers.

Linux-x86_64
NVidia driver: 367.57

This looks like a hw problem because no one else has it.
