[R-SIG-Mac] graphics problem from Macintosh system software

[Richard M. Heiberger]

No idea at all.  It happens randomly.  I have noticed it since June
2012 when I first started using the Macintosh.  This is the first time
I saw it with R-3.2.3 so I decided to
report it again.

My guess is that it is deep in the Macintosh device driver software.
