i've opensuse 12.1 , gnome 3, 64-bit, installed on my desktop.
I've always this annoying error every time i run a java application ( as Jdownloader ).
If i press the super-key, and gnome shows all my open windows, i've to see this little black window with two white points inside it. ( I can't attach screenshot )
I know, it's not the end of the world, but it's very annoying for me.
Have i any chance to solve this trouble ?
