I notice what appears to be the same thing in Precise. In case it helps, my specifics:
- everything is visually fine from boot to presentation of login screen - after I type my password, before the gray intermediate screen comes up (between login and session) in Unity 2d, my screen flickers briefly and then for about 5 seconds shows multiple corrupted password dialogue boxes scattered around the top of the screen - my hardware is old ATI IGP stuff - one other thing that I notice that is different than 11.10, and that is my session background also appears as my login background; that is, I chose the "watch gears" background for my session, and afterwards, whenever I see a login screen, it also has "watch gears" -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/933322 Title: LightDM graphic corruption with ati and nvidia Status in Light Display Manager: New Status in OEM Priority Project: New Status in OEM Priority Project precise series: New Status in Unity Greeter: New Status in “lightdm” package in Ubuntu: Triaged Status in “xserver-xorg-video-ati” package in Ubuntu: Confirmed Bug description: LightDM shows graphic corruption after entering password and pressing Enter.
