KD-85XG8596BAEP stuttering issues

[Busmusen]

Since the TV was new there has been a really annoying stuttering issue every 15-30 second on both Netflix and HBO, the screen and sound  freezes for a 1/3rd of a second, it's more noticeable on action packed scenes..

Motion flow is very much off

It's not a connection issue bcs it's a wired 250/250mbit fibre connection to the TV.. and the other sony Android TV runs fine on WiFi.

I have tried to:

-Factory reset the TV (this made my USB stick to stop working with this TV)

-Restart the tv

-restart my network

Any ideas?

My father's TV was new out the box with already installed Oreo 8 he had the same issue on Netflix so I disabled ipv6 Lan in his router and now it's fine .I also did the same to my TV after Oreo update and now is fine apparently there is something in the Oreo update that don't like ipv6 ..I have two Sony TV's one is still running on android 7 that have no issues and  yet the one TV I updated started having the same issues as you
