I built a tree with D3 where the nodes are png files with a transparent background; most of them look okay in Safari, but the monochromatic ones (white and very pale grey) have some bizarre rendering issues--in particular, they have a blocky black partial outline (like a drop shadow, almost) when zoomed out with scale(), and at certain scales the lines connecting the nodes bleed through the images & the images appear washed out. The other icons (exactly the same, except coloured, instead of monochrome) all display correctly. 5.1.7 on Windows 7; Chrome/IE/FF all display correctly.
Can you attach/link to a testcase (the smaller/simpler the better!)
We don't have test case and if we have similar issue, we would have newer bug report or it might have already being resolved, so I am marking this as 'RESOLVED CONFIG. CHANGED'.
