Scrolling when in game does not work at all.
This issue affects everything in game relating to scrolling, such as when you scroll through the menus and hotbar.

You have a click and drag the window slide bar and you have to use the keyboard shortcuts for the hotbar items.

When playing using an XBox One controller, the controller can scroll using the LB and RB buttons.

The scroll wheel works in all other aspects of my PC, including the Java Version of minecraft.
