In order to reduce the file size of the image, I use .jpg format to save most of my background images. The flicker occurs when doing page turn transition from one scene to another.
I use the same image but in .png format, everything works well. So is it a bug of iPad2, can I do something to avoid it? My iPad2 iOS version is 4.3.3.
I also find a bug report here: http://www.cocos2d-x.org/issues/863. Seems it is rejected.
After reading the comments in bug report, the only solution comes to my mind is that create a new Sprite class which is only used to jpg images while disable alpha blending when drawing itself. Any better solutions?
