I do not experience problems.
I tried to make a self contained version of your script.
The following should fail for you.

sz = [4800,3600];
pic1=peaks(max(sz));
pic1(:,:,2) = pic1';
pic1(:,:,3) = fliplr(pic1(:,:,1));
pic1=pic1(1:sz(1),1:sz(2),:);
imagesc(pic1);
hold on;
plot(sz(2)*rand(100,1), sz(1)*rand(100,1),'ro');
hold off;
print -dpng test.png

Could you verify if it is size related?

What happens if you choose sz = [480,360] ?
