Don't know how much Wade is using
'com.jogamp.opengl.swt.GLCanvas' or our NewtCanvasSWT class, if at all.

However, we do overlay ourselves a native window on top of the SWT Canvas one,
actually similar to what the SWT own GLCanvas implementation does.

Yes, the SWT implementation has outstanding bugs
and issues like yours (layout z-stacking etc) are quite possible not be covered.

See our bug list for SWT here:

Everybody is welcome to tackle these bugs!
I may only find time for those later this year,
since they are of low-priority at least for me and our projects right now.

Cheers, Sven
