Hi, Both Inkscape and Mozilla have bug reports concerning an error in the feTurbulance random algorithm.[1][2] This bug results in squares being drawn for certain seed values. (Example[3]) There is a discussion of the problem on svg-developers.[4]
The Inkscape bug report traces the problem to a divide by zero when both values in the fGradient table are zero which occurs for some seed values. A couple solutions are proposed in the comments.
