I switched from Ubuntu 14.04 with Unity to OpenSuse 13.2 with GNOME 3.14 desktop.
The problem is when I change the cursor theme, GTK and Java SWT apps accepts the new theme while Java Swing and QT still on the old theme.
I changed the theme using Gnome Tweak Tool.
/usr/share/icons/default/index.theme. You need to change the line:
Inherits=<name of cursor theme you are using>
For example, I'm using a theme called Openzone Ice Slim, so that line looks like this for me:
Inherits=Openzone Ice Slim
That will change a default fallback cursor theme for all users, and I think there is the file with the same name in
~/.icons/default/ which will change the default cursor per user.
