[Qt-interest] Have any recommendations of enhance the GUI speed of using GraphiscView/Scene/Items ?

[Sherif Ghali]

I'd like to chime in with a brief example where the user interaction
with QGraphicsScene and QGraphicsItem is quite flawed despite the
simplicity of the code, but since it's not exactly what's discussed
here, I'll avoid hijacking this thread and will post separately.
