I have the same problem-- scrambled menu on Netflix. It's the only streaming service that scrambles (and it only does it on TV, not on my phone or laptop). Furthermore, it began when I had Time-Warner/Spectrum, but this month I switched to Verizon/Fios and it is still scrambling. Netflix is the only constant here, so it has to be a Netflix problem. I've tried all the solutions mentioned above, and it still scrambles-- usually the menu, but sometimes also the show I start playing. When I called Netflix, the asked me -- get this!-- to list the channels it happens to. My reply was to ask them if they knew how much work that would involve-- they have hundreds if not thousands of programs-- and that, furthermore, I wouldn't do that if they paid me. I'm a customer, not tech support. (Sorry not to be of any help in solving the problem; just adding to the chorus.)
