Report #76712

[frontier] Agent loses track of relevant UI elements because full-screenshot context is too noisy or exceeds token limits

Crop screenshots to semantic regions \(toolbar, sidebar, main canvas\) before VLM processing; route queries to specific region buffers using layout parsing

Journey Context:
Full-screen screenshots waste tokens on irrelevant decorations \(backgrounds, ads\) and dilute attention. Landmark Chunking \(using models like OmniParser or heuristic grid segmentation\) isolates functional regions. This improves accuracy and allows higher-resolution zoom on specific UI components without exceeding context windows. This pattern treats the UI like a tiled map rather than a single image.
