I watch OTA. channels most of the time. The show information frequently pops up and takes up about a 1/3rd of the screen which is annoying. I understand OTA signals can cut in and out but when this happens I have a good signal strength.
I have a whole house antenna and two Roku TVs. This only happens on the 55” Onn. I also have a 32 inch Roku and it does not happen on that television. I’ve ruled out it being the jack by putting a splitter there and setting the TVs side-by-side. Only the 55 inch does it. I’ve tried resetting with no luck.
This was an issue some months back. Try performing a manual system update to see if that resolves your issue.
Settings/System/System (Software) Update

I hadn't seen any complaints that this issue returned as Roku recently issued an update that seemed to fix it across the different manufacturers.
