Description Phil Beauvoir CLA 2021-04-06 06:35:42 EDT 
Ubuntu 20.10 running Wayland
Eclipse 4.18

When performing a DnD operation with a DropTargetListener, pressing a modifier key (Ctrl) should generate a dragOperationChanged event. This is not being generated on Wayland.

Run Snippet91 [0] with the following lines added so that the event is logged to the console:

@Override
public void dragOperationChanged(DropTargetEvent event)
    System.out.println(event);
}

- Run the Snippet
- Select a tree leaf and start a drag operation
- While dragging press the Ctrl key a few times

Under Wayland the dragOperationChanged event is not generated.

Sorry, that should be Ubuntu 20.04.

Can you please try with nightly 4.20 SDK build? 4.18 is not the latest version.

Tried it with I20210405-1800 and the problem is still there.

Also tried with Ubuntu Wayland 21.04 (beta). Same.
