Chromium tab crashes if mp4 video with GPU acceleration

Question

I maintain a distro that runs chromium called FullePageOS.

I added gpu acceleration, but now mp4 video crashes the chromium tab when its viewed (mpeg works).

How can I fix this?
Alternatively how do I figure out exactly what is causing chromium to crash?

More info:

I am using kernel 4.4.34-v7+ and Chromium Version 51.0.2704.91

Its a bug I can see on FullPageOS RC1, here is link to the bug with conversation on github.

Update: Terminal output is:

libGL error: MESA-LOADER: failed to retrieve device information

(chromium-browser:1964): GConf-WARNING **: Client failed to connect to the D-BUS daemon:
/usr/bin/dbus-launch terminated abnormally without any error message
MESA-LOADER: failed to retrieve device information

[end of stack trace]

Steps to reproduce:

1. Download FullPageOS RC1 (md5) (or you can build devel branch)

2. Set up wifi/connect to ethernet

3. After boot vnc, or press ctrl+tab to open a new chromium window (Chromium starts at boot)
4. Put the URL: https://graftechnology.s3.amazonaws.com/videos/matthew-west-promo-android-tablet9.mp4

Expected: video should play Result: get an "awww snap" page

Notes: if you add the tab to FullPageDashboard, and the tab is not selected, you can hear the video playing, but once you switch to it so it becomes visible it crashes.

Note: I also tried runnign with --enable-logging --v=1 and look in chrome_debug.log, and could not find something about the crash (I am not sure what to grep for)

There is also a thread about this bug in raspberrypi forum

Here is the status of chromium in the gpu tab:

Answer 1

Upgrading from 56.0.2924.84 to 60.0.3112.89 and using Debian Stretch seemed to have solved the problem. You can download a distro and see its working with version 0.8. And how it fails in version 0.7.

Here is the current gpu tab:

Note, there seem to be disabled items in the detected problems, perhaps one of them is the one that cased the crash:
