Crosswalk 14, which includes the Skia fix, is available now for building in the Intel® XDK. You are no longer stuck with Crosswalk 7!
Special thanks to Ashley, Egyptoon , lola and everyone who participated in the thread. It was this community that helped the Crosswalk team identify the bug and get it resolved. Numerous people provided APK's, device types, and OS versions that replicated the problem. The Crosswalk team reproduced it with a known device/app and found the fix. It's been resolved now in Chromium source too.
