Hi all!
I am using a scene, which there i paint some texts with QPainter::drawText given the position, the rectangular and the text itself. It seems that when painting 12 texts, and move the scene in an animation, it quite flicker on my embedded device.
When i animate by moving a big picture on it, it has no problems doing it. Why is that and where is the difference?
Is it a good idea to make performances better with QPixmapCache ?
