• Resolved issue that caused tracking latency within apps to increase over time

  • Fix for service crash after disconnecting/reconnecting in HMD mode

  • Fix for errant disk full message in App Home on Windows


  • We support the image hand in robust mode, but it is not recommended to use full-on image passthrough in bright lighting / robust mode

  • Pausing/Resuming Tracking can cause the FPS to drop. The workaround is to Disconnect/Reconnect the device to bring the FPS back to normal.

  • Bone direction vector points in the wrong direction. It should point toward the distal end of the bone.

  • Images cannot be extracted from serialized frames

  • Device.isFlipped is always false

  • Avast! Antivirus can interfere with Leap Motion Service installation (disable shields to work around)

  • Secure WebSocket (TLS) on Linux Chrome requires running with --ignore-certificate-errors (caution: this also affects non-WebSocket services)

  • Chrome on Windows 7 sometimes fails to respond to emulated touch points – to fix this, click inside the program with a mouse

  • The sphereRadius and sphereCenter functions of the Hand class are unstable when the hand is fully open

  • Tracking quality is lower when making a fist or with only one finger extended

  • Tracking may not work as well with bracelets, rings, watches, sleeves, etc

  • Linux does not support background apps or onFocus callbacks


  • The latest version of the Oculus firmware limits bandwidth for the DK2’s built-in USB port, which harms the controller’s performance. For now, we recommend using the free cable extender bundled with the mount to connect the controller directly to the computer.

  • Tracking performance may degrade when closely facing large reflective surfaces like white walls or infrared-reflective curtains. (This is a broader issue with V2 tracking that we’re constantly improving on.)

  • Tracking degrades when arms are held directly away from the body (i.e. elbows straight).

  • Some poses are not currently tracked reliably in head-mounted display (HMD) mode (e.g. pinch/rotate, 3- and 4-finger poses).

  • Minimized or out-of-focus applications using the HMD policy flag can affect the service state. Close such programs before switching back to non-VR apps.
