Don’t want to spam the responses, but I’m aware I’m not the only person needing help, so while I wait, I try to figure stuff out on my own as well, creating new info.
So, I tinkered with a few movies on sevwral platforms as well.
Streaming to work on the Plex Windows Player worked well for “The 5th Element”
Streaming the New “Godzilla” to my phone or Xbox One X (Local) caused artifacting in the image.
I tinkered with a setting, turning off Direct Play and Direct Stream, and the artifacting is gone (but buffers forever).

States that there was a defective Transcoder at one point, and this is an OLD and updated Plex Server, so it’s likely that I’ve installed most of the update revisions over time.
I’m going to get started backing up my media to a Cold Storage drive, and I’ll wait to hear back from you @ChuckPa to proceed.
I’m thinking that I may just need to re-install Plex to get rid of older errors that may be lingering around, but I’ll wait to wipe the current install until I hear from you.
