UWP HTML/JS application problem after Windows Fall Creator's update RRS feed

  • Question

  • Having a weird issue in my UWP HTML/JS application after system automatically updated to Windows Fall Creator's update(1709).

    Frame reader's tryAcquireLatestFrame() method returns NULL every 3 to 10 frames (randomly), resulting in a heavily stuttering app output.        

    function reader_DepthFrameArrived(sender, args) {

                var depthFrameReference =;



    depthFrameReference is NULL.

    It worked all fine on the previous (1703) Windows version. What happened after the update??

    Any help on pointing me out to a possible solution is highly appreciated.

    Kinect v2. Driver version: 2.2.1610.17001
