Synchronization points for state information

A system comprising:

• at least one processor;
• and
• one or more computer-readable storage media including instructions stored thereon that, responsive to execution by the at least one processor, cause the system to perform operations including:
• executing a first thread to generate a change to a visual state of a graphical element, the graphical element represented by a corresponding node in a first display tree of the first thread, the first thread further configured to emit a synchronization point that includes an indication of the change to the visual state and that persists in a valid state at least until a second thread retrieves and processes the synchronization point to update the visual state of the graphical element in a corresponding node in a second display tree of the second thread;
• and
• executing the second thread to process the synchronization point to determine the change to the visual state, update the visual state of the graphical element in the second display tree of the second thread, and to render the graphical element to apply the change to the visual state based on the updated visual state of the graphical element in the second display tree of the second thread.
