NuI+ bug
 

when ever I put wow into windowed mode or alt tab out. and come back there is a white border around my UI. if I do a /reloadui it corrects the issue, but its kinda irritating, if anyone has a fix that would be awsome!

That's not nUI, it's a well documented Bliz bug. You can read more about it in the nUI F.A.Q. listed here on the forums. ;)
