Building geometry mismatch issue

[dp12024]

There seems to be an issue with some building geometries not exactly matching with the basemap (e.g., openstreetmap basemap in QGIS). An example is a building located at -37.80471163, 144.97150367. See a screenshot below of the building. The building geometry seems to be distorted. For example please take a look at the leftmost edge of the building, which is supposed to be straight but is distorted. Wondering if it is something related to the accuracy of parsing? I'm using Windows and pyrosm v0.6.2 and am just using get_buildings() function based on a osm.pbf file that I downloaded for the region.
