GPU process does one-off EGL initialization on linux.
This should get WebGL working on EGL/GLES2 ARM boxes again.

I'll enhance the EGL logging code so it outputs the error code so we can track down the problem. I should get it committed some time today.

Thanks for tracking that down. It is specifying EGL_RENDERABLE_TYPE = EGL_OPENGL_ES2_BIT in the config attributes for eglChooseConfig on gl_context_egl.cc:90 though.
What it could be is you have two versions of libEGL, one corresponding to v1 and one corresponding to v2 and it is dlopen is loading the v1 version for whatever reason and using it to make the first context. Can you verify?
What's the linux versioning convention for libEGL. Should it be dlopeninglibEGL.2.so ?

Thanks for that. Glad it's working now. I'm working on a patch now.

Specify client version 2 when creating EGL contexts.
It was doing this already for SecondaryEGLContext but not for NativeViewEGLContext, which made it default to EGL version 1 on non-ANGLE EGL implementations.
I also fixed ANGLE upstream in r468 so it fails to create a context unless version 2 is explicitly requested.

Description
Chrome Version (from the about:version page):
Is this the most recent version: yes
OS + version: arm
CPU architecture (32-bit / 64-bit):32-bit
Window manager:
URLs (if relevant):
Behavior in Linux Firefox:
Behavior in Windows Chrome (if you have access to it):
What steps will reproduce the problem?
2.
3.
What is the expected result?http://www.khronos.org/webgl/wiki/Demo_Repository should run properly
WebGl examples
What happens instead?
An error
[3142:3142:7982823576:ERROR:app/gfx/gl/gl_context_egl.cc(225)] Error creating Pbuffer: 12296
and a pop-up dialog saying is webGl context enabled?
Additional information:
WebGL used to work in chrome-r52380. looks like patch applied on chrome-r52388(http://code.google.com/p/chromium/issues/detail?id=45898 ) broke the chrome-webgl build.
