I can confirm this very annoying bug with i915 driver (on Lenovo x220). It creates all sorts of graphical difficulties in Chromium (no vsync, no interpolation of fullscreen videos, and of course no WebGL)
LIBGL_DRI3_DISABLE=1 is a good fix. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1371834 Title: Chrome causes segfault in i965_dri.so Status in Chromium Browser: Unknown Status in “mesa” package in Ubuntu: Confirmed Status in Debian GNU/Linux: New Bug description: Running chrome 38.0.2125.66-1 on Ubuntu 14.10, on Lenovo X230 When I start a new instance of chrome, it cannot enable WebGL.
