Title:
Weird screen glitches when opening a session
Status in “unity” package in Ubuntu:
New
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.
