SWT_AWT DPI scaling [message #1858043]

I'm using SWT_AWT to run NASA WorldWind in an Eclipse application. There's a problem when using DPI scaling other than 100%. The SWT_AWT.new_Frame() method sets the frame size using the current DPI scaling. That's wrong, I think. The embedded frame is sitting within another SWT composite, and it gets is size when the outer composite layout runs.

I don't see any way to turn that off. So the effect frame size is wrong with scaling other that 100%.

Am I missing something?

Did old JVM work?
It is noted that combining SWT components with AWT/Swing is going to get trouble. I used to get warnings from JVM. So I changed program not to use AWT/Swing components.

I've decided that this is a bug in SWT_AWT: https://bugs.eclipse.org/bugs/show_bug.cgi?id=581656.
I haven't tried an older JVM. I'm using jdk-11.0.12.7-hotspot.
