dashed line is moving (graphic artifact on Mac Retina display)

Hi, when dashed (or dotted) line is plotted, if I move the cursor on the figure, the dashed line is moving (visual artfiact, see the attached file)

I think this problem is unique to iMac display (Retina 5K, 27-inch, 2017, Mojave 10.14.6).

Any fix would be grealy appreciated. This artifact makes my eyes very tired and I can't give up using dashed/dotted line.

Thanks

I would like an answer to this as well. I'm using a mid-2014 MacBook Pro Retina. The moving lines started when I redefined the XData and YData of the Line object to be larger. At first I thought it was because I had accidentally duplicated some of these values, but the problem persisted when I removed the duplicates. Interestingly, I noticed that the problem disappeared when I reduced the LineWidth from 1 to 0.5 (but not, for example, 0.6).

This is so odd and it happens to me too on a Windows laptop with an attached external monitor. I am neither manually editing XData and YData, nor have duplicated lines. I happens when I use the command stairs instead of plot and only when the figure is maximized. So strange!
