[XeTeX] FakeBold vs TikZ

[Wilfred van Rooijen]

Hi all,

I can confirm this issue with

XeTeX, Version 3.1415926-2.5-0.9999.3 (TeX Live 2013)

on linux and both Evince and Acroread as PDF viewers. There definitely is a dot. I guess the issue is solved in TeXLive 2014.

By the way, if you add a an extra circle to be plotted, that extra circle does not have dot in it. The dot is not on (0,0). If you change the color of the node (\draw[red]), the dot remains black while the circle becomes red.

Cheers,
Wilfred
