This is still happening. I may found a way to reduce the lags, @CastagnaIT let me know if it make sense.
I disabled the options to sync watch status with Netflix and also the library sync. I still have lags but seems much less.
Are there other services that reach out to Netflix while watching? just a theory but maybe that what causes the lags. (unless I'm the only one having them)

this might help if you have a low-end device or a slow cpu

this does not affect anything, there is no process running
the process will be activated when the update starts only (scheduled time)
when you set to Disable only disable the context menus in the items of video lists

> Are there other services that reach out to Netflix while watching?

all addons/scripts plugins that manage videos could create threads that are "passively" active
so receive/process information while watching your videos (of other addons) without you being aware
you should try also disable all other enabled addons

I found the issue.
some time ago I added some netflix titles to my list, and "export" them to library.
They didnt appear at the library no matter what I tried.
I saw now in the event log of kodi, that every 3 minutes there is an event "update video library" with those strm in it.
that, combined with the addon "auto update library" caused the stutters. 
Once I disabled this addon, it was fixed. (but I still had those events, probably its from the netflix addon)
I now removed those titles from my list.
Just for your information.

library clean or scan (update) is a heavy operation for the device when the library contains many elements
setting this function every 3 minutes is unsuitable
it doesn't make much sense to keep the cpu busy often

the problems of some exported titles not appears in kodi library is due to the screaper did not recognize the titles
is explained here, Enable NFO files export setting:

can you give me a link of this addon "auto update library"? or menu steps to install it from repository?
