I've been running CM 13 for a while on my moto x play. I've had no problems with it until this last update and installing some themes.
After updating it, I downloaded some themes, applied them and received the "system ui has crashed" or something message on screen.
After this the wallpaper has turned black (no change if I try to change it manually), the animations for the lower bar (triangle, dot, square) are not showing, dragging the upper status bar takes several seconds to show, when my cellphone is unlocked the response of the system is extremely extremely slow. If I drag my fingers up to unlock it, it will take a long time. The funny thing is besides these, there are no problems apparently. If i go to settings, things run smoothly, chrome, facebook, whatsapp, etc. but any interaction with: status bar, lower bar, locked screen is extremely slow.
I mistakenly thought it was an update bug or smth and reinstalled a past update, but issues remain.
What happened and how can I correct this?
