The partial rewrite of the face engine in 8.5.0 is about 95% accurate based on our testing and multiple user reports. What you are experiencing is the first report of poor performance in 8.5.0. The face engine is completely rewritten for the next 8.6.0 release. Can you provide more information, please? How many different people have a confirmed face in your library? How many confirmed faces do you have in total? Did you remove ALL faces including confirmed, unconfirmed, and unknow and restart with face detection, or are you retraining with faces that were found with older versions of digiKam? To make sure you are using all the correct face models, I'd like you to delete the directory where we download the face AI models. If you are using the AppImage, look for a directory called facesengine and delete all the directories under it. The directories should be name yunet, dnnface, and shape-predictor. After the directories are deleted, please restart digiKam and it should download all the models again. Please let me know if you have any questions.
