: Business intelligence tools (like Tableau or Power BI) embedded inside corporate portals.
Here is a comprehensive technical guide explaining its architecture, triggers, and deployment strategies. Understanding the Viewerframe Architecture
– A directive to completely redraw the entire viewer frame, rather than just a region (dirty rectangle). A "full refresh" discards any cached or partially updated pixels and forces a full repaint from source data. viewerframe mode refresh full
: Developers often trigger a "refresh" by:
Use incremental updates (dirty rectangles) during normal operation, and invoke a full refresh only when errors occur or on a timed interval (e.g., every 300 frames). : Business intelligence tools (like Tableau or Power
Never hook a full refresh directly to a high-frequency event. Implement a 3 to 5-second delay (debouncing) to ensure the system does not enter an infinite refresh loop.
| Scenario | Use viewerframe mode refresh full ? | | :--- | :--- | | You see visual ghosting or "dirty" pixels | ✅ Yes, immediately | | You just changed a global lighting model | ✅ Yes | | You are profiling minimum frame rate | ✅ Yes | | You are animating a 60fps smooth rotation | ❌ No (overkill) | | You are on a battery-powered laptop | ❌ No (power spike) | | You have 10,000+ dynamic objects | ❌ No (frame drop) | A "full refresh" discards any cached or partially
With , this optimization is bypassed. The application or driver forces a complete redraw of the entire viewer area on every vertical sync (v-sync) or frame interval. Each new frame triggers a full repaint, from the top-left corner to the bottom-right, without any region skipping.
