I noticed that by modifying
the FileGDBs created by ArcGIS PRO in QGIS:
1. saving is particularly slow;
2. I often lose data, i.e. if I have an active data selection and I try to
update only the selection, QGIS updates the entire dataset resulting in
data loss.

Hi Totò,
as you already know, QGIS handles ESRI File Geodatabase layer via the GDAL/OGR library. The GDAL/OGR library has two different drivers for the ESRI File Geodatabase forma: the built-int driver "OpenFileGDB" [1] (which is available on all systems) and the "FileGDB" driver (available on Windows through OSGeo4W) which depends on the ESRI FileGDB API SDK [2].
Using which driver does the issue occurs?

How do you update the data?

I think you should inform the GDAL/OGR developers about the issue. Since you experience the issue often, it shouldn't be so difficult to provide a sample ESRI File Geodatabase layer and exact steps in order to replicate the issue.

Best regards.
