I have trouble filing a bug (there's no apparent way to create an account).
The reproducer is in the first message of this thread.

In the meanwhile, I managed to find the root of the problem: it's the code dealing with `superlayer` in fixCALayerLayout() of OSXmisc.m (in jogl/src/nativewindow/native/macosx). Commenting out the whole block before `if( NULL != subLayer ) {` fixes it. I verified that it also fixes my application with Java 13. It may also help with bug 1378.
