In iOS 9, the CIFilter "CIGaussianBlur" no longer seems to work.SKEffectNode *effectNode = [[SKEffectNode alloc] init];effectNode.shouldRasterize = TRUE;effectNode.filter = [CIFilter filterWithName:@"CIGaussianBlur"];[effectNode addChild:nodeToBlur];effectNode.shouldEnableEffects = TRUE;This code worked in iOS 8. Now, instead of blurring the node, it scales it disproportionately.
