For a few weeks, maybe months now, I have had problems with my 8K TV - 75" Q900RA (2018) - with the 4K content on YouTube. The 1080p. works fine without any problems, so it is only 4K and 4K60Hz videos that does play but often stops and starts to buffer and then play and then stops again, and then plays and stops....
Furthermore, what is strange that I also have some permanent picture problems with 1080p. videos on a specific YouTube channel that has been mentioned in here - it is on the official Conan O'Brien YouTbue channel, and the Chuck Norris interview - in which also have the same picture problem on the TV's own internet browser, but NOT when playing on my MacBook in the same WiFi network !
I also notice when I am experiencing problems with the 4K content on YouTube that the manoeuvring the menu to check the resolution settings, or just stopping or pausing takes some seconds before the TV responds.
The problem with the 1080p on that one YouTube channel is disturbances in the picture that keeps popping up... Here is the video that describes the exact same problem I have on my TV, which is not a problem when watching the 1080p. on my MacBook.

...and here is a link to the actual Chuck Norris video on the offical Conan O'Brian YouTube channel: https://www.youtube.com/watch?v=SE2ZrK7A4TI
I check the internet speed - through the TVs own internet browser and the download is over 100 Mpbs - and upload over 10 Mpbs. - and as mentioned no problem when watching 4K on the TVs own internet browser.
I have the 1334.0 version on the TVs own firmware - and the YouTube app-version is web_20230628_10_RC00 - plus I have the YouTube Premium subscription.
Also do not reply that I need to get a Apple TV or Chrome-cast when watching YouTube - as they have still not released 8K version to this date (July 2023), and it seems to not be planned in the nearest future either.... The TV has an built in YouTube app, which should function well with my internet speed and paid subscription.
I am speculating now, but can this issue be related to the built in HVEC H.265 codec hardware which my TV has -it does not have the AV1 codec - which used to only be a problem when trying to watch 8K content on my 8K TV, as it was impossible when YouTube started showing 8K videos on their platform with the AV1 codec only ? Can this HVEC/H.265 codec be the root of the issue I am experiencing ?
My 8K TV have to this date NEVER played 8K, and been up until recently only a functional 4K60Hz TV at its max - but now even the 4K videos on YouTube are messing up again.
