So I've found certain slow motion scenes cause this to happen. After the slow motion pay it is like only half of the frames are displayed. Once I stop the video and start it again everything is fine. It happens on local streaming and through streaming services such as Netflix and YouTube.
I can even rewind the show and reproduce the issue at the same spot. So I tried the same spots of the same shows using my Xbox and the issue doesn't happen. So I don't think it is an issue with the TV itself.
I have tried a factory data reset and the issue still happens. Any ideas?
EDIT: Found out it was some settings in my TV causing the issue.
Does your tv have the "Enhanced Motion" setting turned on? Can you use your shield on a monitor or other screen to confirm its not the tv.
