I have it not activated and its not only on lockscreen. Each time when i install android 8 the phone generlly is laggy. On android 7 there i have no problem such like this. Also notification of mi home do not work on android 8. On my other two phones which have installed android 7, notification works of mi homeremove face unlock
On my second mi5 i have installed miui 9 global 8.3.29 beta and on my mi5X i have also installed your rom 8.4.4. On mi5x i have no such problems like on one of my mi5 where i have these problems. Maybe there is only a problem by mi5 with your rom?do you install only our ROM or also any other mod or root?
