You can see the screenshots. We are using latest version of dash.js and playing the video on Samsung Tizen TV, 2019-2014 tv models.

Can you share the subtitle file that generates this output?

[krishnakumar-ViewLift]

we don't any external file, and this is live event so cc file is embedded in live stream. When running on chrome that verticle line not coming. Only on samsung tizen tv.

@krishnakumar-ViewLift Perhaps you could extract the subtitles from a segment where this occurred, and post those?

This sounds like a platform (Samsung Tizen TV) issue rather than a dash.js issue. For WebVTT dash.js uses native rendering functionality of the underlying device by default. I suggest you try the custom rendering functionality as shown here: https://reference.dashif.org/dash.js/latest/samples/captioning/vttjs.html
