Reproduced on OS X 10.7.5 (GTK+/X11) with Inkscape 0.91 r13725, 0.91+devel r14430 (tested with cairo 1.14.2 and cairo git master).
- turning off caching does have no effect;
- the rendering glitches don't reproduce if zooming out further;
- removing the stroke (or converting it to path) does reduce the rendering glitches.
