Weird Lion Login Window issue (window in top left corner)

Hi All,

Has anyone ever seen this happen? Do you know what could cause it? it does not seem normal to me. Thanks!

i also have a lion mac 13'' and this is happening to me as well. I haven't done anything because nothing is actually wrong with my machine so far. I presume that it is a glitch.

i wonder if restarting it will help?
