Thanks Thiago, I understand that my program has a high memory footprint, which has a lot to do with my implementation, so I just wrote the demo for comparison. QML and widgets use different technologies, can I understand the meaning of no comparison between qml and widgets programs. BTW, I re-uploaded my demo in https://bugreports.qt.io/browse/QTBUG-104322. In fact, my problem is that there are two: Why does qml have higher memory usage than widgets.（At present, I am also analyzing through source code and memory detection tools） If optimized based on qml demo, how to make its memory usage consistent with widget demo or similar.
