Screen responding strangely after having being changed

I have a bug after I have changed the screen of my Xperia 10 Plus. The old screen was partially broken but it was responding properly. With the new one, it is responding for the majority of the manipulations, but I cannot use it from the top to close for example the applications and from the bottom to have the menu of the applications when an app is already open. But I can minimize the applications with the gestures from the sides of the screen. Does anybody already have such a problem ?
