Bug Description
Since the last reboot, from time to time, randomly, the screen gets filled of short vertical black lines (segments), for a fraction of a second or few seconds, then gets back to normal.
Now a few minutes have passed and apparently it has stopped doing it.
Prior to this last reboot some updates had been installed (that's why I had to reboot), and I had never ever seen this happen before, so this may be a regression in some recent update.

To apport's question "Is the issue purely graphical? (it will be reported against Compiz" I answered "yes", so I don't understand why it has been reported against Unity allthesame
