    It would be best to isolate the problem using a minimal compilable example.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.

    Oopps, I'm a bit dizzy late at night. I've produced a minimal example and figured out that the problem is with the line:

    Qt Code:
    1. self.setCacheMode(QGraphicsView.CacheBackground)
    To copy to clipboard, switch view to plain text mode 

    Removing it solved the problem. I just tought it could speed up the performance of drawing grid.

    Thank you for your help.
