Flickering object on drag

romyrome2005

Hey guys, my actor's graphics is flickering when I try to hold it. But when the object is being dragged along it doesn't flicker at all and it looks normal. Also when it is colliding with another object it also flickers. By flicker i mean that the object goes haywire (rotating randomly) but stays in the same position

i used tshirt booth's tutorial on youtube to make this

thanks
