When using IDE styles (not classic Windows), there is some repainting-issue of the outer-borders of the editor: after some time the small bands on the right of the vertical scrollbar and below the horizontal scrollbar are getting messed-up. Minimizing and restoring the main window fixes this but after a while the issue is back. This issue was also there in previous versions. See the red marks in this image: https://postimg.cc/p9LT0Q9f
