Value mismatch in QGIS

[advaccaro]

The values displayed in QGIS differ slightly between the original data, the clipped data, and the clipped and projected data. The layers appear to be slightly shifted from each other (e.g. 1 cell up or 1 cell to the side).

Hi. I think this issue is related to QGIS or ESPG standard. But I don't have prove. Do you have some insight on this?
