Status: RESOLVED WORKSFORME

Lately I've found a lot of HTML5 youtube videos keep getting stuck.
If I do a refresh/hard refresh, it usually gets stuck in the same place.
For example, it usually gets stuck at: http://youtu.be/tuFiC_PzjXY at 1:38
Refreshing and trying again only seems to create more of the media decoding threads.

Attaching output of top -H and a stacktrace of all the theads in gdb.

Using gnome-ubuntu 14.10, and Nightly 38.0a1 (2015-01-27)

Note that I switched to a new profile for a while, to get around this bug (it only reproduced on that profile). I went back to the default profile a bit later, and I can't currently reproduce the problem anymore. It was probably resolved by another change. (I am on nightly, btw).

So we can probably close it if no one else can reproduce it.

FWIW I've been having similar problems, also on 64-bit Linux, since upgrading to 37.  It's sporadic, happens on more than just YouTube, and doesn't stop when I close what I think is the offending tab.  Seems to just go for as long as it feels like, no matter what I do.

Glad to hear it's fixed in Nightly, but that's still a few months away for me...  :)

Assuming fixed with the new MSE.

Hasn't happened in a long time, so I assume so. Thanks!
