I have a jailbroken iPhone 4s running 5.1.1. I jailbroke it when Absinthe 2.0 came out and it worked perfectly, till recently, when black spots appeared whenever I opened the app switcher or an icon folder. When I open the app switcher, the space that 2 center icons would take up look normal, but the places where the first and last icon would go are simply black, not the normal gray thatch like design. Same thing with folders. Is there any way to fix this?
