Hi,

I'm just wondering if WebGL is still disabled in 14.04, even though we
are on chromium 44 now? I wanted to enable WebGL just to see if I could
watch 360° Youtube vids then, and now noticed that it no longer works at
all, apparently due to this Ubuntu change.

I realize that lots of crashes are GPU-related, but IMHO ripping that
feature out of chromium completely is bad, as most chromium GPU features
are blacklisted (by Google) on my AMD system anyway because they tend to
cause problems. If it's too much of an issue, maybe GPU stuff could be
blacklisted for all drivers, and those who would like to use WebGL etc.
could manually override the blacklist in about:flags? That's what I have
done repeatedly in the past, although I'm well aware that any strange
behaviour could be related to disabling the blacklist.

Title:
  Chromium 43 fails to use hardware acceleration

Status in chromium-browser package in Ubuntu:
  Fix Released

Bug description:
  After installing package chromium-browser 43.0.2357.81-0ubuntu0.14.04.1.1089 hardware acceleration becomes disabled.
  I had no problem with previous chromium version.

  Console output:

  GPU process was unable to boot: GPU access is disabled in chrome://settings.
  Disabled Features: all

  Actually GPU access is *not* disabled from settings.

  Workarounds like "--disable-gpu-sandbox" or "LIBGL_DRI3_DISABLE=1"
  didn't helped at all.
