Just to add to this - I can see this problem on macOS.
On Linux and Windows, ctrl+mouse moves the display up and down one page at a time without problem. The Jqt term session is a QPlainTextEdit control and AFAIK we don't have any special mouse handling for it. An even simpler QPlainTextEdit control is textview, e.g. on macOS try textview i.60 20 This also exhibits the same glitches. I wonder if this is a Qt issue?
