This bug doesn't exist in 0.48.1
I saw it this morning in rev 10355 on Kubuntu
Couls someone confirm it before I fill it on Launchpad ?
When blur is combined with a Composite "in" some vertical dark lines are shown on rendering and exporting to bitmap.
If vertical blur is set to zero the lines change to dots.
If a little amount of black is added they disappear (here I decrease luminance and that works too).
Seems similar to the issue reported in
- Bug #790192 "Regression in rendering of Gaussian Blur" https://bugs.launchpad.net/inkscape/+bug/790192
Your attached example tested and exported to bitmap with Inkscape 0.48(+devel) on Mac OS X 10.5.8 (i386), default settings: the rendering errors have been
- not reproduced with 0.48.1
- not reproduced with r10140
- reproduced with r10145
- reproduced with r10365 (cairo 1.10.2)
- reproduced with r10365 (cairo 1.11.2)
The regression seems related to the faster rounding routine for the Gaussian blur committed in revision 10144, see also: http://thread.gmane.org/gmane.comp.graphics.inkscape.devel/36273 http://bazaar.launchpad.net/~inkscape.dev/inkscape/trunk/revision/10144
Except that the faster rounding has since been disabled... So r10365 already does not use the faster rounding anymore. There are a couple of other minor changes in that same revision though, so perhaps one of those is the culprit. I'll try to have a look asap.
