This issue is not reproducible in ArcGIS Pro 2.9.2.
For tracing performance, turn off snapping for any layers that are not being traced. This can be done dynamically anytime while sketching from the List By Snapping tab in the Contents pane. Refer to the documentation for more information: https://pro.arcgis.com/en/pro-app/latest/help/editing/disable-snapping-for-a-layer.htm.
