Thanks for the follow-up, John. I'm running Windows 10, have a 27-in screen with a resolution of 2560 x 1440, and text is scaled at 125% (I presume the latter is what you meant by "DPI"). Just to be clear, I can run the same model under Netlogo 6.22 and
then immediately afterwards under 6.3, without changing anything else, and graphics quality between the two runs is very noticeable, particularly in line plots.
Also, sorry for the double posting earlier.
