On my new Roku Ultra (2020 version), both Youtube and Netflix are showing only a static image after selecting a video to play, while the audio keeps going on. Issue is only temporarily fixed after a system restart from the main menu.
I already switched my display type from Auto-Detect to 1080p and Auto adjust display refresh rate to Off.
I go through a system restart multiple times a day and also tried reintalling each app as well and completely powering off the device. I’m running it on a basic sharp 1080p tv. Both device and apps are up to date
