Introducing SteamVR 1.21

Desktop View quality-of-life improvements and OpenXR tracker support

Update Highlights

Today's update features a couple of quality-of-life improvements for Desktop View and OpenXR support for Vive Trackers.

Desktop Views now have a button to minimize all windows on the desktop. This is especially useful when users have a single monitor and the scene app displays a full screen window. We also added more graceful handling of the situation where a window that SteamVR is unable to interact with gains input focus. We detect this scenario and trigger the Task View, which restores the user's ability to use the laser mouse.

We added an implementation of the XR_HTCX_vive_tracker_interaction extension for OpenXR that will allow developers to support Vive trackers in their OpenXR apps. UE4 developers can use our plugin to get started. Unity developers can read through this thread for more information.
