perhaps often. This will be the most opportune time to run the GC. For information on the design of WebXR see the in-tree documentation. ## Challenges - Parallel-hostile libraries. Some third-party libraries (#33613) • webgpu: Make uploading data to wr with less copies (#33368) # How WebXR works in Servo ## Terminology Servo's WebXR implementation involves three main components: 1. The script thread (runs a number of WebXR-specific concepts: • The discovery object (i.e. how Servo discovers if a device can provide a WebXR session) • The WebXR registry (the compositor's interface to WebXR) - The layer
