I just switched to TikZ 3.0 and was used to hatch rectangles similar to this thread
actually the example given in the accepted answer https://tex.stackexchange.com/a/54465/8042 was my favourite way. Nevertheless, since TikZ/pgf 3.0.0 the hatches look quite strange, cf. Chapter 60 (p. 674) in the most recent manual.
Does anybody know how to get the old north west lines back?
