In current stable you have to override the blacklist for it to enable
gpu acceleration anyway, so this is more of a feature request to
investigate why this happens with dri3 but not with dri2. For non-
working webgl this is probably a little bit more serious.
On current google-chrome-unstable on a fresh profile with default settings gpu acceleration is enabled.
When it is manually enabled via chrome://flags and checking "Override software rendering list", this has happened at least since one or two stable versions, probably always.
Symptoms:
$ google-chrome-unstable
ATTENTION: default value of option force_s3tc_enable overridden by environment.

this is repeated two times and chrome://gpu has these Log Messages:
GpuProcessHostUIShim: The GPU process crashed!

But with LIBGL_DRI3_DISABLE=1 google-chrome-unstable it works without issues.
Ivy Bridge, xorg 1.16, xf86-video-intel with sna and mesa both from
recent git.

It's more or less intel specific. With (dri3) offloading to a radeonsi
GPU all the gpu stuff works. But directly running it on intel doesn't.

For the people only reading this bug report:
In IRC keithp found the cause.
With dri3 temporary files are created with O_TMPFILE.
The chromium sandbox does not allow creating temporary files with O_TMPFILE.
So another workaround for now is to use chromium/chrome with the --no-
sandbox option (which will possibly reduce security).
There's a corresponding bugreport at chromium that was not publicly visible before, but now is:
https://code.google.com/p/chromium/issues/detail?id=415681#c9
Close this with NOTOURBUG/WONTFIX?

It's getting fixed in chromium, so no action is necessary for mesa:

"who has the long-term fix almost ready."
I suggest keeping this here open until chromium is actually fixed and
then closing it.

Resolved upstream - their sandbox allows the creation of the necessary
