Mac OS v10.8.2

 

Have any of you experinced buggy logon screen resolution?  I have attached some pictures below.  When I wake up my iMac from sleep, a logon screen comes up but from time to time it's gets buggy.

 

When buggy happens, all I see is my Desktop background, but there is no logon screen.  As I start moving the mouse icon, it begins to erase the desktop background and logon screen appear from behind.  The more I move the mouse, the more I see it.  After I click a username, then enters the password... everything is normal again.  I wonder if this is known issue.

 

(I have marked out the usernames for my privacy)

    Hello,

     

    To post pics you need to use the tiny Camera icon in a reply to upload them... drag & drop will disappear as soon as you post.

    Resolution

    Move the mouse or trackpad cursor over the center area of the login window so you can see the user icons. Click on the icon of the user that you would like to login as, type in the user's password, and press Return.

    If the login window is configured to show only the name and password fields, type in the user's name and password into the fields, and press Return (even if you cannot see the rest of the login window).

    Additional Information

    This issue will not occur if the display is not sleeping when the account is logged out. Use the steps below to confirm that the account is not configured to log out automatically while the display is sleeping:

    1. Open System Preferences > Security & Privacy > General.  Click the padlock to unlock the preference pane and enter your admin password. Click the Advanced button at the bottom, then see if the option "Log out after N minutes of inactivity" (where N is the number of minutes) is enabled.
    2. Open System Preferences > Energy Saver and configure Display Sleep to occur after the account is logged out, by dragging the slider to a number of minutes that is greater than N was set to in the previous step.

    Important: If automatic log out is not needed, disable "Log out after Nminutes of inactivity" in System Preferences > Security & Privacy > General. This will also prevent the issue.

    Thank you so much for posting this.  I have been having this same problem for several weeks now and it was making me crazy thinking that my OSX system had been corrupted.
