I do have "Use hardware acceleration when available", still chrome://gpu
shows a lot of disabled/software-only stuff.

THIS IS NOT F***ING FIXED.

Watching videos consumes a lot of CPU, and so does even just opening a page with a few small animated gifs.
This is f***ing ridiculous.

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:

  $ chromium-browser

  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.
