Installed 15.04 ISO downloaded about a week ago. On a default install (which uses Unity, I imagine) had a situation on several occasions when logging out of an account or shutting down the computer, the graphics go berserk. The display rapidly cycles from right to left, like an old TV that's out of alignment.
