I set everything up as you suggested. I also updated Youtube to the latest version an hour ago. Everything was fine but as soon as I selected the 4k resolution the problems started again. Green squares and restarted box. Never had any problems in the past few weeks with 4k resolution. Not even warped video issues (squeezed left and right). the only change on my U22 was the update to the V8 firmware, the update of the Youtube app and the update of Youtube Vanced. I do not know what to think...
I can understand your disappointment. My extensive testing got me to recommend not to update to V8. This said, YouTube has been making frequent updates to the app. Not knowing what might be behind Vance, I have to assume it somehow uses the engine supplied by the YouTube app updates.
In short. Making the changes I recommended to the settings of the YouTube app partially solves the problems regarding the squishing of the videos, yet I still got some set backs needing to restart some videos after they got affected when I advanced the video moving the slider to the right. Not always though. Regarding 4k I haven't noticed any trouble, but I always tested after having cleared all cache and closing all apps. I will test further.
Anyway, SmartYoutube has always been my preferred choice for 4k content. I am willing to find out what might be now causing all this with the other apps.
