I tried what you have suggested on Galaxy S2 and it doesn't work for me (i.e. GPU raster is off).

I also try to reorder XWalkPreferences.setValue or to remove super.init() but I got the same result. Am I doing it wrong? Please advise. Bnaya, I don't know if Chromium dev workaround the problem, but Galaxy S2 works with GPU raster and I didn't notice any issue. However, in Crosswalk < 15 GPU raster is off (and we get much worse performance).

For version before crosswalk 15(version since 12 days ago), you have to manually add "XWalkPreferences.setValue(XWalkPreferences.ANIMATABLE_XWALK_VIEW, false);" before new XWalkView. Otherwise gpu raster will be totally disabled.

We use Cordova as a wrapper and Crosswalk as the runtime library for our app. We don't use specific Crosswalk code or do any special customization, so I'm not aware to ANIMATABLE_XWALK_VIEW and I may need to read about it a little bit more. Anyway, here is the situation: 1. We use "clean" Crosswalk, no tweaks and no Java code involved. 2. On devices such as Galaxy S2 GPU rasterizaiton is off on Crosswalk and CSS animations are very laggy. 3. On devices such as Galaxy S2 GPU rasterizaiton is turned-on on Chrome and CSS animations are much better. 4. According to my last check from today, when using Crosswalk 15 (crosswalk-cordova-15.44.366.0-arm) on Galaxy S2 GPU rasterizaiton is turned-on on Crosswalk and CSS animations are much better. Our code wasn't changed for that of course. What is the difference between Crosswalk < 13 to Crosswalk 15? I need to check also what happen in Crosswalk 14.

This is true for all devices. Overall, performance looks similar, maybe slightly worse but I can tell exactly because the debugging tools are not working properly. Galaxy S2 (Android 4.2, CyanogenMod): when I opened the app, after the splash screen, I got a screen with a solid color of the HTML background color and then black screen after few seconds. After few times I tried to reopen it, the app was loaded normally. Again I couldn't measure it exactly because of the problem with the debugging tools, but the FPS might be now slightly better (the game runs with 50-60 FPS). The good news is that CSS animations looks much better and indeed raster is now on! Did you fix this in Crosswalk 14? Nexus 10 (Android 5.1): works even worse. FPS dropped from 4 FPS in Crosswalk 13 to about 0.5 FPS :) (previously to Crosswalk 13 it was ~60 FPS). CSS animations are very leggy (but the problem in CSS happens in Chrome too). Crosswalk for this device seems to be completely broken. Overall, this is a Canary build and it's unstable so it's hard to judge about the issues above. I couldn't determine if the performance bug (https://www.scirra.com/forum/crosswalk-performance-mega-thread_t125842) is fixed - I'll try to check it also on Galaxy S3. Side note: upgrading to Crosswalk 15, I needed to change the code of the class that inherits from CordovaActivity to override onXWalkReady(). This change in the API is annoying since now we need to toggle the source code each time we are testing different Crosswalk version.

I'm not sure if it's possible, but adding the capability, when the APK is built by users, to selectively drop features (i.e. modular Crosswalk) will practically integrate Lite to the main branch.

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.

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.

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!
