--- Comment #19 from Aaron B aaronbottegal@gmail.com --- 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.
