   An array of random vectors or a lookup texture could do. if you just want to blur you should use a Gaussian kernel or even just use a smaller mipmap.

   well there is not much you can do, brice told you the options. you can pass random vectors as texture or as uniform array... or you could use noise approximation and generte on the fly (quite costly so). you can experiment with offseting the texcoord prior to sampling the normalmap. although you will risk discontinuities…
