6 Blink and Compositor Handshake in View Transitions

The provided text explains the technical handshake between the Blink rendering engine and the compositor during a web view transition. To ensure visual continuity, the system captures a snapshot of the old DOM state using unique resource identifiers before updating to the new content. During this critical capture phase, Blink temporarily freezes rendering or throttles frame production to prevent graphical glitches, employing a timeout failsafe to avoid permanent page hangs. The process is managed through specific communication requests, such as Save, Animate, and Release, which coordinate how the compositor stores and blends these visual states. Finally, the documentation details how geometrical data and surface IDs are passed back to Blink to correctly position and animate the transitioning elements.
