Yes, it is specific to you (or some Macs). I'm not sitting in front of my
iMac, but when it displays on my Linux box, the result is fine.
There are several variants of x11(): I am assuming this is the CRAN build
and type="cairo"? I tested the latter (and my self-build), and it should
be rendering on the Mac so the actual X server would be irrelevant. My
test was for 10.5.5, though.

I've no idea whether this is specific to X11 on the Mac, but maybe it is
well to note it here first.
x11()
