Sign-In causes temporary display distortion

[Zach]

Signing into Ubuntu 12.04 Beta 1 causes temporary screen distortion. Signing in after boot, causes this issue. Signing in, then sigining out, then signing back in also will cause this issue. This issue was not present in 11.10, started immediately after 12.04B1 upgrade. Attached picture of distortion. Note, that this picture was taken by signing out, then signing in, and taking a picture with camera after hitting enter. Elements of windows that were closed, prior to sign-out are visible- notably by the mouse cursor where a Shut-Down title-bar appears, that was the last window open before signing out.
