- there is a list r-sig-mac for MacOS enquiries.
- There is no R7.0 nor R6.3.  We can guess you meant 2.7.0, but there is
   no 2.6.3 either.  The posting guide specifically asks for accurate
   version information. 
- there is no reproducible example here.

Now, considering the use of image() on quartz() in R 2.7.0, there is a 
(equally vague) bug report and thread at

https://stat.ethz.ch/pipermail/r-devel/2008-May/049650.html

that seems similar to your comments.  Simon Urbanek has made some changes 
to quartz() to alleviate this, so please try a current R-patched build.

But this does not apply to pdf(), although the effect is seen in some PDF 
viewers (and is a bug in those viewers).
