Windows Binary Not Re-Painting Correctly

[bpetty]

I don't really know what the problem is... but when I compile my program and run it on another windows machine... it is very very chopy.

On the machines that I compile it on it runs very smoothly, but that is not the case on any other machine.

I think it is a painting issue. I did override this function:

void MainForm::paintEvent(QPaintEvent * /* event */)
{
    QPainter paintGo(this); // Green Circle
    QPainter paintStop(this); // Red Circle
 
    showServiceStatus(paintGo, paintStop);
}

void MainForm::paintEvent(QPaintEvent * /* event */)
{
    QPainter paintGo(this); // Green Circle
    QPainter paintStop(this); // Red Circle

    showServiceStatus(paintGo, paintStop);
}

To copy to clipboard, switch view to plain text mode 

I have a timer that goes off every half second. when that happens it calls a function that does an "update()" to repaint everything. It appears that things are ONLY getting repainted when this timer triggers. Am I doing something wrong here?
