Qt image viewer simple modification

I have a Qt (QGraphicsView, QGraphicsScene, and QGraphicsPixmapItem) project that simply loads image from file, and add it to the qgraphicspixmap item. you can zoom in/out the pixmapitem using setTransformation() function.

Its very basic program, and it works extremely well under Windows, but under Linux, if I open the a large image (over .5 mb) and load it in full size it works OK, if I change the zoom either in or out, it becomes apparently slow (the mouse movement, and the scrolling of the pixmap)

I need to see if anyone has any experience in fixing this, or can give me a valid response why this is NOT working correctly, and how to fix this.

I believe this should be very simple problem for someone who know what they are doing and should not take a lot of time to figure out the solution.

I will be waiting for your bids and feedbacks

Best regards,
