Bug Description
Inkscape 0.48.1
Windows xp service pack 3
I start with a circle, the size is irrelevant. I then duplicate said object(or path) and remove fill, then apply a stroke. Apply a blur to that. Then duplicate the original object and select the newly duplicated piece as well as the stroke with blur, making sure the stroke is below, then set a clipping path. Now I have tested this with all sorts of different objects and such and it is only apparent as far as I can tell on anything that is from a circle to a full square, irregular shapes do not have this problem nor do full unaltered sqaures. The problem being that the blur is always slightly more 'focused' at each point of the compass. The very northern part, east point and so on. It is happening with both the circle object, the square object(with courner handle nodes modified) and the\ same thing when converted to paths. I have experimented with various different thing and always get the same result. I am able to circumnavigate this problem via a bit of tricky work with gradients but it is still a bug. But imo no overtly important :-). Cheers
Could you attach sample SVG files explaining your problem visually, and possibly a screenshot how it looks in your Inkscape?
Do you compare rendering of the blurred and clipped objects in Inkscape, on-canvas, or is this about the exported bitmaps (PNG), other export formats or SVG renderers?
I can't detect an unevenness of the clipped blurred circle in a simple test following your initial description, screenshot attached).
