[webkit-qt] [QtWebKit] Issues with WebGL on top of DirectFBGL

Hi David
I hope one of the WebGL implementors (Andrew / Jarkko) would be able to answer this better…

Not in my experience.

I think QGLWidget was a bit more straightforward - you just share the context with the parent and use an FBO. For most use cases this does not cause drawing issues.
It's probably possible to implement this with a pixel buffer as well - though how would that work in a cross process environment? Right now my thoughts for WebKit2 are to either use EGL images (with Mesa for desktop) or streamline GL commands to the UI process.
