By implementing this extension we are exposing Monado's multi-application support, which was recently merged to master.
In the video below you can see Monado compositing the rendering of Blender's VR view and the xrgears demo displaying a
XrCompositionLayerProjection as overlay. The demo also showcases Monado's ability to deal with multiple graphics APIs as Blender uses OpenGL and xrgears Vulkan to submit its frames.
To enable the extension in xrgears only this small change was required, which enables the
XR_EXTX_overlay extension and passes the
XrSessionCreateInfoOverlayEXTX struct to the graphics bindings `next` field.
The branch of xrgears running as an overlay can be found here.
Thank you Pluto VR for making this work possible!
