Hi,
thank you. I set 25 frame per second. It's better but it's so slow. And if I
increment the x step and the y step of the movement to 2 pixels (it was 1),
I get the same previous bad result.
I presume there should be a better way to do that.
Somebody know?
Best Regards

setFrameOrigin is calling another display method anyway.
