Oh, sorry, I had missed the “lite” part in your original question. Merging Lite to master would mean dropping a lot of features, so Lite will always be a separate release.

It would be great to have the option to remove some unused features and have smaller APK/consume less memory. We are not sure yet if we are going to use Crosswalk lite (for the concerns mentioned above), but it seems mostly wanted to have the fix for Crosswalk 15 (assuming it indeed fix the performance issue) ported to Crosswalk 14/ Crosswalk 14 Lite.

We haven’t discussed this yet, it sounds like you would want it?

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!

You can follow the status here: https://crosswalk-project.org/jira/browse/XWALK-3720 In short, after some back and forth there is a fix in Crosswalk 15 and it will be backported to the other current releases after it’s been verified to work. If you have any chance to try Crosswalk 15 and let us know how it works for you, that would be very helpful.

It seems that setting GPU rastarization off is a big performance hit. In Crosswalk 13 GPU rastar is disabled for some devices (e.g. Galaxy S2) but for the same devices it's enabled in Chrome and seems to work OK. There is a huge difference in performance (specifically, in painting time) when setting GPU rastar on/off. See detailed explanation in https://crosswalk-project.org/jira/browse/XWALK-3614 (my comment from today). Just to extend on this a bit more, we see differences in performance between Crosswalk and chrome (in favor to Chrome) in other places. For example, we see on Nexus 10 (Android 5.1) that our game runs on 4FPS (!) when using Crosswalk 13 and 50-60 FPS on Chrome 43. Up to Crosswalk 10 we had similar FPS (is it related to https://www.scirra.com/forum/crosswalk-performance-mega-thread_t125842?) The performance issue is currently the most painful and critical for us (actually, it's also true for anyone I know that is using Crosswalk, or anyone that intends to use it but doesn't because of performance concerns). I would expect Crosswalk to have a performance at least as good as the corresponding Chrome. Why GPU rastarization is set off (for some device) in Crosswalk 13 but is enabled in Chrome and works fine? Also, is there any improvement in regard to the subject in https://www.scirra.com/forum/crosswalk-performance-mega-thread_t125842? Looking forward to get updates on this. Thanks!
