Hello, Just my observations about this: I think in your example there are several reasons, why the blurred element is still visible or the result is not as expected. 1. second scale is 1100, first scale only 1200 2. stdDeviation="0.001" + transform="scale(1200)" is not small compared to 'one pixel'. 3. I checked the behaviour with other examples and discovered some minor errors in Opera9 (maybe related to optimisation of processing time and used working memory, maybe in parts avoidable, I'm not sure). 4. The adobe plugin seems to stop calculating those filters completely if the dimension of the filter gets too big (width and height attributes of the filter element). Even if it calculates, sometimes remain some smaller errors for really neglectable standard deviations. If you want to look into details, it might be useful to animate width and height of filter. I think, in a real world with limited capabilities of computers one cannot expect a complete perfect behaviour for those filters in an acceptable time. Therefore one has to take a very close look, why something is not completely perfect - sometimes it is only a compromise with current technical possibilities. Of course, sometimes it is a mixture with minor errors, too ...
