App launcher changed after update and can't see icons

I'm using Cyanogenmod 12.1 with the deafualt app launcher and deep darkness theme. Something happened and the app launcher screwed itself up and now I can't read the names of the apps and have to scroll down instead of side to side.

I reverted to a backup using TWRP and it was normal at first but after some automatic updates it went back to this messed up app launcher. I've never changed the app launcher before and don't know how.

I'm used to seeing this, the half on the right.
