With Eclipse Neon and sirius 4.0.0, when a container mapping with gradient color is moved on a diagram, it causes rendering issues.

The problem appears under Windows but not under macOS.

See image attached.

Can't reproduce under Linux, with either GTK2 or GTK3 (see attached screenshots). This seems specific to Windows.

VSP
Comment 5 Laurent Fasani CLA 2016-06-30 10:21:40 EDT 
Steps to reproduce:
* import the attached VSP into your workspace
* create a new modeling project with an ecore containing a EPackage with an EClass
* create a diagram and move the EClass container -> bad feedback

Some pointers for if/when we tackle this one:
* The actual figure used seems to be created by org.eclipse.draw2d.FigureUtilities.makeGhostShape(Shape).
* Unfortunately this is a static method whose invocation is hard-coded. At first glance it looks like we would need to override methods in many figures to replace it it with something else (which is still to be determined).
