Some progress to report:

I downloaded JOGL 2.3.2 (the current stable release). The jogl-all.jar file in this release seems to fix the bug with the "wandering" GLCanvas.  

I still get this warning:
2019-11-05 09:12:40.954 java[29310:4710461] WARNING: NSWindow drag regions should only be invalidated on the Main Thread! This will throw an exception in the future. Called from (

That's presumably I'm not using any of the resources in the 2.4.0 build that I started off this thread with.  But since 2.3.2 seems to fix the bad behavior I encountered, I consider the problem solved, until I upgrade to a version of Mac OS that converts this warning, as promised, into an exception.
