This happened to me again when playing http://people.mozilla.org/~jmuizelaar/4k/Bosnian%20Landscapes%204K%20(UHD)-goQMXfiS-dA.mp4

I wasn't able to reproduce the problem after restarting firefox

[Tracking Requested - why for this release]: This gives a very bad user experience.

This is really to reproduce when playing the embedded youtube video on https://roystanross.wordpress.com/super-mario-64-hd/ .

Here's a screen recording: http://tests.themasta.com/tmp/supermario64videoframecorruption.mov
It gets really bad about a minute in.

Interestingly, recording the video actually affected the corruption. That leads me to believe that this bug isn't caused by us reordering the frames, but by us presenting corrupted frames, and some of those corrupted frames just happen to contain a past frame that we show again.

Tracking for 39+. 

Is this reproducible in earlier versions? Florin, would you like to try to find a regression window?

I'm afraid I cannot reproduce this. I've tried on three different machines running OS X 10.8.5 (miniMac), 10.9.5 (Macbook Retina), and 10.10.3 (iMac). Since this appears to be related to MSE I've forced the HTML5 player (https://www.youtube.com/html5) and then opened the URLs from comment 0, comment 1 and comment 4. However, in all cases the videos played without any issues on latest Firefox 40 Nightly, Firefox 39 Aurora and Firefox 38 Beta.

Either there's something I'm missing here or there's more to reproducing this (like the profile needs to get into a certain state to start reproducing the issue - I used new profiles).

Got to reproduce it very easily on a 2011 mac mini with AMD 6630M... fix is in bug 1153469

Looks like this was fixed in 38, 39, and 40 in bug 1144401. Untracking this duplicate.

Ah, I mean, in bug 1153469!
