So has anyone else come across this??
If not then I will file a bug for JIT in webkitgtk on arm7.

Thanks Ross, Trevor,
With webkitgtk 1.8 I was having issues with opengl present.
It seems not to be the case here.
My screen is completely blank.
I have discovered that the page fails to render due to
javascript.
Disabling JIT solves this issue.
The example below fails to render if JIT is enabled.
It will however render if I uncomment the 'alert' statement.
Test
Page Rendered
//alert("JavaScript works")
Is there anything you would like me to test??

I don't know. But in the mali case it is possible to have mali provide egl/gles1/gles2 and have mesa-gl provide an opengl-only solution as a fall-back for any non-egl/gles1/2 apps (or at least theoretically it is).

I'm hoping that someone contributes a "null" backend to libepoxy so we can build GTK+3 without OpenGL in the future, but nobody has done that yet.

[yocto] Webkit2gtk opengl issue
I am working on an am335x based project, with a webkitgtk program on the screen, displaying a simple webpage. I want to use a standard yocto kernel, which I believe means I must do without the SGX hardware acceleration until an open-source driver is available. Thus in fido I had added opengl to DISTRO_FEATURES_remove This worked with webkitgtk 1.x The webkitgtk 2.x recipe also specifies opengl as optional. However it depends on gtk+3 which depends on libepoxy which requires virtual/egl. Is this an oversight?? Is it possible to build webkit 2.x without opengl??
