I had cairo dock installed and it worked perfectly. At first i thought it may have been something to do with the screen resolution or translucency. The problem was CAIRO DOCK , some of its dependent packages. After removal of it, i enabled translucency again, set my screen size back to normal 1920X1080,and that has fixed it so that Kaffeine now works correctly. Daisy Dock is working but not worth having installed as it will not allow me to drag and drop app launchers to it anymore. Seems no dock will other than Cairo. So you can have one but not the other it seems. All good anyway. Kaffeine Solved.
