Tetriser check the "layoutTransition2.1.1" , in properties of the plugin , you can set the Transition speed for all transitions.
— sorry i did not fix the probleme , but if you want to use the Fade animation , i advice you the V1.2 , i did solve that probleme on that version, but in this versioni can't because it does not use the same type of making the Transition
sorry again :'(
