Login screen has solid gray background color, not the usual textured pattern?

[dandanapple]

I did migration assistant from a Lion 2009 MBP to my new Lion Retina MBP, and one of the glitches was that the login screen changed to having a flat gray background color.

I later upgraded to Mountain Lion, and this did not fix the problem.

I tried messing around with NSTexturedFullScreenBackgroundColor.png, but that didn't help. That file appears to be the correct textured background introduced in Lion, but the screen is still just the gray.

I have included an attachment showing a picture I took of the screen.

Your help is appreciated.

This problem has never been resolved for me.

Are you using Filevault?

I deactivated FileVault and the screen login started "normally" without gray background color, but i have another problem actually i have only one user and appear another two, i know that one is the guest user, but no the other one...some one has an idea?

The grey screen comes up with FileVault2 enabled. It's the screen where you need to enter your password to unlock the encrypted hard drive data. After you enter your password the hard drive is unlocked, Mac OS boots, and it logs you into your account automatically. You won't be able to change that grey screen because Mac OS hasn't even booted yet. Or it has only very minimally.
