As an example, if im looking at my PC im connected to via teamviewer and i zoom in so i can actually see things, i then drag my mouse to the left side (towards power plug-in port) and it'll 'scroll' all the way to the left until i move mouse away from that edge. Now if i want to scroll to the right and i drag my mouse off to the right, teamviewer's view stops just before the camera and yet the mouse keeps going all the way like normal. Because teamviewers stopped expanding its screen all the way correctly it ends up with a very flawed and difficult to use auto 'scroll'.
