If i let my mi box go up sleep on it's own with kodi open, when it wakes up the Kodi UIs are all chopped up. If i put it to sleep manually and wake it right back up it fixes it.
Anything suggestions? Btw, when it happens it only affects Kodi. Android home screen is fine.
Yes I remember I had exactly same issue but I don't remember how I solved it :)
I am back on Marshmallow from horrified experiences of those ill fated Nougat betas so that may solved it. Also, go to developers options and check Always awake option or something like that.
