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.
