Offset in face mesh

Hello!


working in an AR app for our product we realized that there is an horizontal offset on the face mesh when we overlay the mesh over the video image. Not sure if it's an offset, but especially the left side of the face (left on image, right of the face) there is sometimes about 1 cm even more off. We checked the code and doesnt seem to be any error. We thought it was a detection issue for some faces, but it actually happens to everybody. Did anyone experienced the same? any solutions?
