To clarify, is the issue that the cut-out covers the toolbar? If so, I recommend going to the settings menu (the last tab to the right with a controller icon when you open your inventory) and scrolling down until you see the setting for "Toolbar padding". Adjust this to a higher number, as you do, you will see a red line on the left side of the screen showing how far out the toolbar will extend.
Another option is to look for the checkbox labelled "Vertical Toolbar" and un-check that. This will move the toolbar to the bottom of the screen, although you may need to adjust your controls around it if you end up preferring that setup.
If you are having a different issue, please let us know!
