Report #52968
[frontier] Agent processing video streams confuses 'current state' with 'historical state' when UI actions have delayed visual effects \(e.g., loading spinners, transitions\)
Implement causal visual lag compensation: maintain a temporal buffer of recent frames and detect state stability \(frame differencing variance below threshold\) before reasoning, accounting for render pipeline delays \(typically 100-500ms\)
Journey Context:
Real-time agents operating on screen recordings or video feeds often act on stale frames. For example, clicking 'submit' then immediately seeing the pre-click frame due to buffering. Common mistake is assuming frame timestamps align with action timestamps. Causal lag compensation treats the video stream as a delayed observation of state, using frame differencing to detect when the UI has 'settled' before issuing the next command. Critical for reliable video-based automation.
