It sounds like you're asking about ensuring that a (likely a custom UI component or an iframe viewer) correctly reflects the latest data or state—specifically, how to refresh it after an update occurs.
- Legacy equipment still in operation (potential security risk).
- An attempt by an external actor to probe the device using legacy exploits.

If you see viewerframe mode refresh updated frequently, your system is working hard. Here is how to make it work smart.
Implementation notes (methodical)
- Distinguish mode changes from data changes – Not every data update requires a visual refresh.
- Use asynchronous refresh for heavy frames to keep UI responsive.
- Cache decoded frames when switching between analysis modes on the same frame.
- Implement refresh suppression when the viewer is out of focus or hidden.
- Log refresh reasons – Helps debug performance and redundant updates.
