1216334 - HTML5 video causing kernel panic and crashes on Mac OS X

Status: REOPENED

(Core :: Audio/Video: Playback, defect, P5)

Description

[Patrick Seiter]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:41.0) Gecko/20100101 Firefox/41.0
Build ID: 20151014143721

Steps to reproduce:

1. Have two Firefox windows open at a time across two different monitors, preferably with the second monitor connected through a DVI-Thunderbolt converter.
2. Start watching an HTML5 video, most frequently happens on YouTube.


Actual results:

Black or white rectangles separated by about 10-20 pixels will start flashing on either my external monitor or my internal monitor.  Sometimes I can disconnect my Thunderbolt connector before it crashes, but many times it will just crash with no warning.


Expected results:

It shouldn't crash my MacBook Pro.

Might be related to bug 1175804?

My videos never turn all green. Sometimes it will cause a weird rainbow effect that I can't really explain. It happens for less than a second and it's like there's a rainbow around the edges of all the objects in the video.

Might be related to Bug 1213447. OP doesn't give enough information for me to say 100% we're the same issue. I'm also on OS X 10.11 as of Saturday, but I received the same error back when I was on 10.10.

Also should have mentioned that OS X has never once given me a message that there is a graphical issue going on. Here is my about:support graphics section:

Is this still reproducible when you set media.hardware-video-decoding.enabled=false in about:config?

I'll try it Anthony. After I posted this bug, I installed:

https://addons.mozilla.org/en-us/firefox/addon/youtube-flash-player/

And I haven't gotten kernel panic or crashed ONCE. I'll disable the plugin and change this config setting. I'll report how many times I've crashed by the end of next week.

I'll disable the extension*

IMMEDIATELY started happening after I disabled the extension and loaded a new YouTube video. I had white boxes of kernel panic on the right side of the same monitor I was playing the video on.

With hardware decoding disabled?

Apple apparently has a fix for this, so installing the system update when it's released may address this.

Otherwise there's not much we can do unless we add a mp4 sanitizer.
