Rendering engine updates in March for the Windows 10 Technical Preview

Based on feedback from Windows Insiders, we are working to release preview builds more often. Today we flighted the first update to Insiders on this accelerated cadence, which includes the latest updates to our new rendering engine. Due to the change in cadence, this build does not yet include the Project Spartan preview, which will be available in the next release.

Today’s build has a number of updates to the new engine, including new features and improvements to existing features. Some of these include:

In addition, you may notice some features partially implemented and available for testing in Internet Explorer under about:flags. These features are under active development and will continue to evolve in future preview builds.

Watch this space over the next week as we’ll be diving into these in more detail in a series of individual posts. In the meantime, you can try these improvements out in the latest preview by signing up for the Windows Insiders program and joining the “Fast” update ring. To enable the new engine in Internet Explorer on preview builds, navigate to about:flags and select “Enable experimental Web platform features.” We’ll also be updating RemoteIE with the new preview soon. Don’t forget to share your feedback via the Internet Explorer Platform Suggestion Box on UserVoice, @IEDevChat on Twitter, and in the comments below.

  1. I’m developing a web whiteboard and need to use a monitor with touch capability. However, the default behavier of Edge is weird.

    For example, use finger to touch, move to the other point and leave.

    In IE 11 in this version(build 14393) of Win10 and Firefox 48.0.2, above action fired mousedown, mousemove…*n, mouseup.

    In Chrome 52.0.2743.116, above action fired touchstart, mousemove, touchmove…*n, touchend.

    In Edge 38.14393.0.0, however, above action will fire mousemove, mousedown, mouseleave only and triggeed the browser to go last/next page in history.

    I’ve set e.stopPropagation() and e.preventDefault(), but it didn’t work in Edge.

    How to stop the default dehavior of Edge?
