I know that in the past there have been some issues with different modes on the Roku. People have complained about "Game Mode" for example and other settings (such as "Action Smoothing"). Have you tried changing any of those by any chance?

If the same video (coming from the same server) looks good elsewhere, then it's either the Roku Client or the Roku itself. However, in this case, I don't think we do anything other than request Roku play the video. So I am thinking it's not the client.

I just discovered that if I disable allow video to be transcoded on my Jellyfin server , under my profile, the stream is being played using direct play . In that mode the screen tearing effect is not present . However , if I use other client (web,iOS, android tv) and force live tv stream to get transcoded I’m unable to reproduce the issue … Is there a way to get the Roku client to natively direct play this live tv feed ? I know it can , if I disable transcoding . I have already enabled the option to direct play mpeg2 stream under the Roku jelly client options.
