GNOME Bugzilla – Bug 341304
blurs appear shifted by 1 pixel to the left.

Attached is a sample test case. The SVG includes two rectangles, with the bottom one having a blur filter applied. The rsvg rendering appears to have the blurred version shifted slightly to the left. Attached is also a reference rendering with batik which appears to be correct. This is rsvg version 2.14.3 from ubuntu dapper.

The CVS HEAD and 2.14.4 versions don't seem to have this problem. Emmanuel made some changes that might have affected this. I'll be releasing a new version tonight. If you could try it out and report back, that would be appreciated.
The problem is still there with rsvg 2.14.4
2.16.0 still has the problem. Attaching a larger file illustrating this, the shift looks proportionate to the object size, it's not a single pixel.

Comment on attachment 77461 [details] rsvg 2.16.0 rendering (blurs offset) It's noticable the shadow object which is at the exact same position as the baber sheet is offset by some distance towards top and left
