The CPU implementation had the following downsides: - The kernels sizes below 3 did not make much sense, often leading to a full white image. - The way how the total number of pixels in the kernel was calculated quite strangely. From these points of view the GPU compositor behaves more user friendly. There is a versioning code which lowers the kernel size, to match the result prior to these tweaks.
