Bug Description
When I open a session the screen shows strange glitches.
It siplays in a sort of mozaic some parts of the screens of my previous session, even after a reboot, I can recognize in that mozaic some parts of a previous session... (kept in a cache/buffer across reboots ?)
It happened before I installed the Nvidia driver too (at first login, after a fresh install)
This occures after entering the password, straight before displaying the desktop.
I mark it as a security issue because behing able to see parts of the screen of a previous can display sensitive informations.

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.
