Comment 2 for bug 1429861

Reproduced on Windows XP (32bits), Inkscape trunk rev. 14005.
Not reproduced with 0.91.

Note that the patterns show around the 100% zoom level (from 85% to 120%), and that the pattern size decreases when the zoom level increases.
Also note that the same patterns affect the image on the right (the one with frequency set to 1.41) when zooming from 120% to 170%.
