In general for FVG (Friuli Venezia Giulia) there are orthophoto services, Lidar and others that are much more accurate and reliable than Bing Maps Aerial and .gpx produced by GPS devices. See for example the True Orthophotos in https://eaglefvg.regione.fvg.it, also available as a WMS service.
The Strava Heatmap WMS service can very often also help.

In this specific case, your changes slightly degraded the quality of the mapping
