Created attachment 125602 [details] Screenshot of track element example with subtitles rendered three times What steps will reproduce the problem? Open a page with a video with track element subtitles. What is the expected result? Subtitles rendered over video, once per track that has mode 2. What happens instead? Subtitles rendered multiple times. I've noticed this on several different sites, including the IE track examples. I've also seen a mode 1 metadata track rendered (on http://www.samdutton.com/track).

Strange, I am unable to reproduce this in Safari with current WebKit.

Has anyone been able to repro this bug lately? If no, I'm going to close as fixed.

I was able to reproduce it on older chromium builds some months back but not with the latest one. So I think it must have been fixed by some recent changes and we should close this bug.

I can't reproduce this now (in Chrome 21.0.1180.79 or 23.0.1235.0 canary) Not here: http://www.samdutton.com/track/ ...or here: http://ie.microsoft.com/testdrive/Graphics/VideoCaptions/

I suspect that this was fixed in one of Victor's rendering updates. Closing this bug, we can re-open if someone is able to reproduce the problem.
