When I open the file that was attached to this mail (gradient-mesh-4.svgz), press 1 to zoom in and then scroll downwards to where the end result is, I get an image like the attached screenshot. Zooming in or out makes it look right again (as does disabling/enabling blur). I'm using the latest exe-only version from inkscape.modevia.com (built on Oct 20 according to the about box), the selected blur quality doesn't seem to affect this (I tried average and best and both show the same problem). I couldn't find any bug report in the tracker about this problem. Is someone already working on this? (Or is even already fixed?) Or should I file a bug report?
