Milo, have you been able to get more infos for this bug? Do you see a pattern when this happens?

Can you please add the EPS generated by:


x=0:.1:2*pi;
y=cos(x);
plot(x,y)
print("-depsc", "out1.eps")
drawnow("eps", "cat > out2.eps")
drawnow("epsis2d", "cat > out3.eps")


Do you see these artefacts with all plots or only if y is going through zero? Do you see a pattern when this happens and do you have a receipe how to create other plots with this error?

I made a plot using the commands below.  The plot looks good (screenshot), test.png from the print statement does not. It also happens with .jpg and .ps (only ones I hve tested)

>> x=0:.1:2*pi;
>> y=cos(x);
>> plot(x,y)
>> print("test.png","-dpng")
