Black lines on the screen flickering/twinkling. Just at the time of initiation before entering the session, I see a lot of these lines. Then it stops and there is only one. This line never goes away during the session. Rarely I can start without the lines appear. These began to appear on October 18 this year, along with upgrading to Ubuntu 12.10 from Beta 2. When start in Windows 7 I have not this problem.
