How to add a plain GeoTIFF file to the correct position in an XYZ layer?

[ZzWDlyy]

When I try to add an image to an offline XYZ tile layer using GDAL, it seems to be misaligned.

      std::string addFile = fileName.toStdString();
       osgEarth::GDALImageLayer::Options gdalOpt;
       gdalOpt.url() = addFile;
       osg::ref_ptr<osgEarth::GDALImageLayer> imgLayer = new osgEarth::GDALImageLayer(gdalOpt);
       mapNode->getMap()->addLayer(imgLayer);

However, when I open it in QGIS and other GIS software, the position appears to be fine.

Initially, I thought it might be due to the image using the wrong coordinate system, but even after converting it from EPSG:4326 to EPSG:3857, the issue persists. The tile map I'm using is from Google Maps. What should I do? Are there any specific parameters I need to set?
Please help me !
My environment is osgEarth 3.4 with osg 3.6.5.

Can you provide the file you're trying to load so we can take a look at it?

Thank you for your reply. I have identified the issue. The different services of Google Maps may have slight variations in the alignment of their maps.
