QGraphicsScene rendering issue in case of big one with high resolution images

The same scene can be rendered correctly or not.

It depends on actual zoom of the scene.

Please, find a number of images of the same scene but with different zoom. (the window size was the same)

 

Code example:

QTransform zoom; //  class member

QMarkGraphicsView* graphicsView;  // class member

 

void ZoomInCurrentScene()

{      zoom.scale(1.1,1.1);      graphicsView->setTransform(zoom); }
