Report #88928

[frontier] Computer-use agents break when moving between Retina displays and remote servers due to coordinate scaling mismatches

Normalize all coordinate outputs to a 0-1000 integer space and scale to actual screen dimensions at execution time

Journey Context:
Hardcoding pixel coordinates \(e.g., click at 1920, 1080\) fails when the same agent runs on a MacBook Retina display \(scaled coordinates\), a headless Linux server \(different resolution\), or a Docker container \(virtual display\). Developers often try to detect DPI and multiply coordinates, but this is fragile. The robust pattern is to fix the coordinate space to 0-1000 \(or 0-10000 for higher precision\) regardless of actual resolution. The agent outputs normalized coordinates, and the execution layer scales them to current screen dimensions. This allows the same agent to work across environments without recalibration.
