I have found a fix for the video stuttering issue and thought I would share in case others experience this issue.
I had to turn off “allow 50hz” and “allow 24hz” in the Xbox settings because somehow that causes videos to have slight stuttering throughout playback. Keeping “allow display mode switching” checked within the Plex app still allows video to be played at the proper frame rates so all seems good now.
However I still get the green artifacts, and the audio/video desync still seems to be present (although not nearly as often as before).
Hope this helps someone as the video stuttering had been a big reason I had abandoned Plex on the Xbox. However minus a few bugs this is the most stable Plex app across many devices I have. Keep up the good work devs!
Edit: Also please take a look at the topic here No sound from any AC3 5.1 audio track (using audio passthrough)
The Plex app currently will not play any AC3 5.1 audio tracks. Hope you all fix that!
