Hi,

when painting a set of lines using a QRadialGradient as QBrush, I'm having speed issue when fast panning with mouse and when drawing a QRubberBand above the set of lines.

I attach a very simple Qt project that shows the problem.
Don't hesitate to zoom near the focal point to increase the problem.

My question is :
Am I doing something wrong or is there anything I can do to improve it ?

[EDIT] I forgot to say that I'm using Qt 4.7.4 on linux Fedora 14 64bits

Thanks in advance for any suggestion.
