Comment # 19 on bug 81644 from Aaron B

It sounds like the same bug, but I'm not 1000% sure. But I had a few crashes in
Chromium, the only out of place log message is:

ATTENTION: default value of option force_s3tc_enable overridden by environment.
[8923:8923:0731/125646:ERROR:sandbox_linux.cc(302)] InitializeSandbox() called
with multiple threads in process gpu-process

Not what to make of it, but it's something more.
