CEF has re-added support for OSR Accelerated rendering. Relevant commit https://bitbucket.org/chromiumembedded/cef/commits/77c1e82898a7f46164e0b997431318bcf9743592

The API has changed, so will need someone to map the CefAcceleratedPaintInfo structure. I've created a class, so the API won't have to change later if someone wants to submit a PR.
