A Material Design-like theme for GNOME/GTK+ based desktop environments.

Disable GTK+ 3

When the SWT GTK+ 3 UI is buggy and sometimes unusable, You can try to disable the use of GTK+ 3 with the SWT_GTK3=0 environment variable when you start eclipse:

SWT_GTK3=0 eclipse

Another option to achieve the same effect is to add the follwoing to /usr/lib/eclipse/eclipse.ini.

--launcher.GTK_version
2

Those two lines must be added before:

--launcher.appendVmargs

Also note that if you do this, the Javadoc pop ups do not get rendered properly anymore if the package webkitgtk2 is not installed.
