Error of cocos2dx [ios]

I have found one problem in cocos2dx.

In iphone project, i have a sprite have a dimension 600 x 500. which moves across screen. (deloy in device). sprite blink and blink.

when i move a sprite have a dimension 200x200, (deloy in device), everything’s ok

i think cocos2d-x doesn’t support a sprite with big dimension move.

Anybody help me

Nobody faced this problem?? when i move with body of box2d, body also blink, maybe because opengl?

Try the solution described here: http://www.cocos2d-x.org/boards/6/topics/27144?r=27234#message-27234 (2d projection)

i set pDirector->setDepthTest(false), everything’s ok
