Chrome causes segfault in i965_dri.so

[Joel Stanley]

Running chrome 38.0.2125.66-1 on Ubuntu 14.10, on Lenovo X230

When I start a new instance of chrome, it cannot enable WebGL. I have reported that bug separately to chrome at https://code.google.com/p/chromium/issues/detail?id=416207

I suspect the cause of the bug is in mesa, as dmesg contains evidence of a segfault:

Status changed to 'Confirmed' because the bug affects multiple users.

[Gérard Bigot (gerard-bigot)]

Found [1] here a workaround :

run chrome with :

   LIBGL_DRI3_DISABLE=1 google-chrome

makes webgl come back.

[Tito (tito-webtito)]

I can confirm this very annoying bug with i915 driver (on Lenovo x220).

It creates all sorts of graphical difficulties in Chromium (no vsync, no interpolation of fullscreen videos, and of course no WebGL)

 LIBGL_DRI3_DISABLE=1 is a good fix.

I tried the "fix" described in #3 and sure enough, I was able to use Google Maps with Earth view. With out the export, it just Satellite view and regular map view only.

This happens in chrome-stable 38.0.2125.111-1, chrome-beta 39.0.2171.52-1, and chrome unstable 40.0.2209.0-1 when browsing chrome webstore (with this graphics card).

It does not happen when browsing chrome webstore with chromium 37.0.2062.120 or firefox 33.

Btw. Those result were from a test in ubuntu 12.04.5 on both the 3.13 (trusty) and the 3.2 (precise) kernel and libgl1-mesa-dri 8.0.4-0ubuntu0.7

[zob (zob)]

Just tested this with the kernel from vivid (3.18rc2): http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.18-rc2-vivid/

On my system the bug is no longer present in that kernel, i.e. Chrome 38+ doesn't segfault when opening chrome webshop.

[zob (zob)]

Ok. Just tested quite a few kernels.
Chrome 38+ does not segfault when browsing to chrome webshop with the following:
linux-image-3.16.0-031600-generic
linux-image-3.16.1-031601-generic
linux-image-3.16.7-031607-generic
linux-image-3.17.1-031701-generic
linux-image-3.18.0-031800rc2-generic

Chrome 38+ segfaults when browsing to chrome webshop with the following:
linux-image-3.15.10-031510-generic
linux-image-3.13.0-39-generic
linux-image-3.13.0-32-generic
and with every other kernel that I have tested with a version number lower than that.

Now someone can probably say something more intelligent about when it was patched. I'm just a trial and error kind of guy.

NB: Chrome 37 and older does not crash with any of these kernels when browsing to chrome webshop.

Someone is fixing this elsewhere:

[Timo Aaltonen (tjaalton)]

should be fixed by now
