Its a serious bug that I'd like resolves because generates a horrible headhaches: When a layer or a shape change their sizes (camera zoom or camera movements or layer scale, etc) the shading (and his blur) is not scaling with this

...and with the shadow effect we can see that the frame of the photogram (margin or border) generates a rectangular shadow

over the shapes that are in and out of the limits... Are somebody working about this? I hope yes, because I thought that the problen it will be resolves in this version 5, but not... Well, THANKS!
