Ever since last night, my lock screen has had a black bar along the bottom. It used to be all green (my background blurred), but now it seems like the whole screen has shifted up. Any thoughts on how to fix it?
Thanks.

I would recommend resetting NVRAM: https://support.apple.com/en-us/HT204063
I would also inspect your display settings in System Preferences. Make sure your resolution is set to "Default for display".

Try resetting your Mac's SMC.
