The Red Dot is a punishment from the Mathematica Gods for using
the horrible notation { Sin@x } instead of just Sin[x]. Ugh!
Seriously, this is a good one. It is apparently some sort of
Postscript problem that starts graphing where the Prolog ended rather than
where the graph starts. It appears to be device-independent. (It happens on my
NeXT, which generally does well with postscript.)

Yes and Yes.
Steve Christensen has repeatedly said to send bug reports to WRI first.
