I hope this will help some people:
I also have a Logitech mouse, but I've never had Logitech Options. At least, I remember checking to see if I had Logitech Options before installing it (because of a suggested solution that requires turning off a feature, I think it was "Mouse Acceleration"), and not finding it. My scrolling issue appeared many hours into the game.
My mouse and the software didn't seem to be compatible, so I left it alone to try other things. Just now, I uninstalled Logitech Options and some other logitech program, with Add or remove programs. I forgot the name of the other program, but I figured it seemed associated with Logitech Options.
Now my scrolling works great! During the problem, I wasn't even able to click and drag the scroll bar of the specific quest journal entry or shard entry, but I had been able to click and drag the scroll bar that scrolls through the list of journal entries and shards.
