** Attachment added: "Evidence" https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1075539/+attachment/3489896/+files/2013-01-19%2012.24.03.jpg ** Tags added: apport-collected ** Description changed: If the first user locks his session and the second user tries to open his own session, the second user can see images (thumbnails) in the screen of the opened windows (applications) of the first user for some seconds. This can break confidentiality. This problem is sometimes reproduced even after restarting the computer when the system is trying to start lightdm.
