Thank you Francesco for the very quick and informative response! We will test Crosswalk 15 for Nexus 10 and we'll update you as soon as we done with that (is the version with the fix is already available in the downloads?)
We are looking forward to get any update about the GPU rasterization - as I mentioned this is a huge performance hit and has a critical impact on devices that it's turned off. Also, we understand that Crosswalk 14 lite is about to be released soon and we are considering using it (mainly for performance reasons, e.g. hopefully quicker startup time, memory usage etc.) . Is it consider to be stable enough for production apps? If so, why isn't merged to the main branch? Also, are you considering to port the aforementioned fix for Crosswalk 15 to Crosswalk 14 lite? Thanks!
