I can answer part of that, but I can't get access to the older system just now.

Yes, because I can run the same jar under Java 8 and 11. Without the
scale option, the Java 11 window is bigger than the Java 8 one, by
about 1.25x (this corresponds to my system setting)
When I add the scale=1 option to both, they are both the same size
(and the same as JDK8 without any scaling)
I've attached 2 images so you can see what I mean, one is without any
scale option (and I labelled the approx size on this) and the other is
with -Dsun.java2d.uiScale=1.0.
The window title contains the system property "java.runtime.version"
so you can see which is which.

I do appreciate your help on this. It looks like it's coming down to
Intel's graphics driver, do you agree?
