On Canary 126.96.36.199 (and 174) when I play a show on Netflix, I get a black screen. Subtitles and header information show up, but no video. I have tried several shows.I have the same issue in a new Incognito window.
Dev 188.8.131.52 shows the video correctly.
If I bring up the controls, the frame previews along the timeline show up correctly, but moving to a different spot on the timeline still has black video.
