Florian, It was already fixed long ago in 14.04, but you need to enable
it manually:

- Open chrome://settings/
- Go to "Show advanced settings..." -> "System" -> "Use hardware acceleration when available"
- Restart chrome
- Check chrome://gpu/

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

  Actually GPU access is *not* disabled from settings.

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