    • This report evaluates the current bottlenecks in "Viewerframe Mode" refreshing—the process by which an embedded viewport updates its content. Current implementations often suffer from high latency, "flickering" during redraws, and excessive resource consumption. This document proposes a shift from synchronous, full-page reloading to asynchronous, differential updating to achieve a smoother user experience.

    In applications that rely on real-time visual feedback—such as 3D viewers, design tools, or video playback systems—the term “viewer frame mode refresh” refers to how often and how efficiently the displayed image (frame) is updated in response to user interaction, data changes, or system timing. A common pain point is when the refresh feels sluggish, stutters, or desynchronizes from input. The goal of a “better” refresh mechanism is to achieve lower latency, higher consistency, and optimal resource usage. viewerframe mode refresh better
