There have been requests for this since 2014 I do not understand why this is not a thing yet it is so frustrating to deal with the screen auto-scrolling any time your mouse gets anywhere near the edge of the screen.
Solved! Go to Solution.
If you click "View" in the upper-left menu of the session window, there is a option to disable auto-scroll. For me it doesn't remember I disabled it when I start a new session, so I have to disable it every time I connect.
