Screenshot showing issue of print margin with high dpi monitor.

Showing the print margin to 100 with a monitor with high dpi (with an editor with a font customized for consolas 10) makes the print margin appear in the wrong place.

This Bug still appear on version 4.10

I use a UHD monitor and DPI-scaling of 175%

Quick query:
1. How are you measuring the print-margin ? I saw you used a series of '=' characters, can you share more details on this part.

2. Do you see the issue at 175% only can you try 200%. Thanks!

Not painting between columns 80 and 81, cursor is at margin, font is Inconsolata@13pt.

In my case I'm measure it using the status line at the bottom of the window. This is a screenshot taken with the plain Text Editor on 4.17.0.I20200902-1800 with "-Dswt.enable.autoScale=true -Dswt.autoScale=150 -Dswt.autoScale.method=nearest". If I restart without those options, it paints in the right place, and restarting with the options makes the margin paint in the wrong place again.
