Setting program scaling to 70% destroys existing instances of the Notes tool and also causes and dragged panels (of notes tool) to be destroyed. The only way it works is to open a new instance directly in the location you need it, then never move it or change scaling. You can see in the screenshot that the breadcrumbs bar and more gets hidden. Also in the list, the cursor position isn't recognized accurately (this gets worse the closer to the top of the panel you are).
