CIFilter Problems Under Leopard

Is anyone else having trouble with CIFilters producing "poor" images when running under Leopard?

For example, I have an image scaling routine that first applies a CILanczosScaleTransform, then applies a CIUnsharpMask filter to sharpen up the scaled down image. The CIUnsharpMask filter produces black lines around the image. Removing the CIUnsharpMask filter fixes the problem.

I have similar results with other filters such as brightness, contrast, exposure, etc. All of these filters seemed to work perfectly under Tiger. _______________________________________________
