Can you please be more specific? Do you have CSSU installed? "If the phone is locked in landscape the glitch appears" means that if you lock the phone when the desktop is in landscape and then press the power button (with the phone in landscape) you see a delay to show the lockscreen? If you do the same thing in portrait it doesn't happen? What theme/configuration are you using?
