I was excited to find one of my favorite movies on the Roku Channel but it can't be watched. I can only see the upper left quadrant.
I've tried changing video settings. Other channels like Netflix and Disney+ work fine. I've also tested other movies and anime on the Roku Channel and they display normally.
I tried it last night and it looked fine. Which model number Roku do you have and how is it connected to your TV (if it's not a TV itself). If it's a separate box, try switching the input source on you TV away from the Roku and then back and see if anything happens.
