You need to downgrade from miui 10 oreo to nougat, find tutorial on YouTube.
Thanks. I did it.
For someone who has the same problem :
flash to Nougat stock ROM (be careful do not close the bootloader) I used the Miui 9.6;
flash the twrp (I used the original Riva recovery from site);
Do all the wipes, format the /Data ;
flash the Lineage OS and the Gapps and done.

Have some lags too. In the lockscreen and notification bar.
The keyboard, just change to another.
