Rendering Issues with Eclipse Photon on Ubuntu 16.04

If you are using the brand new Eclipse Photon on an Ubuntu 16.04, it can happen that you encounter some rendering issues like the one below.

I start my Eclipse in Ubuntu using the .desktop files with the following environment variable: SWT_GTK3=0. This is obvious not necessary any more. You can either set the value to SWT_GTK3=1 or completely remove this environment variable.
