Overview
Use Traces to hide graphics not needed for the current lesson. Pause when discussing a static finding. These choices reduce visual work while preserving the selected physiology.
The telemetry and pressure drawing paths use stable sampling and reuse data to reduce flicker. If a view looks unexpectedly compressed, check its scale and time window before changing physiology.
A current browser and sufficient viewport space help. Reloading can clear a temporary browser problem, but it also starts a new page visit and may replace the current sandbox state.
