I'm not sure what you're talking about. Do you mean the Inkscape window is scrolling without you touching it?
Inkscape automatically scrolls to whatever is selected. But something would have to be selected for that to happen. Like if you had some rogue object offscreen far to the right, and you used the Tab key to select it, once it's selected, inkscape would scroll to it. (more like jump over to it, than scroll) But it should not be scrolling for no reason. If you can't share the file with us, could you make a video of the problem?
Is your mouse capable of scrolling? Could it be a mouse malfunction?
While waiting for more details, I need to tell you about the new Inkscape forum. I have a message on the index page of this forum, but apparently not everyone can see it (although I tried to make it global).
https://inkscape.org/forums/ This forum is not taking any new support questions.
I can try to help you here, but there are a lot more people in the new forum who might be able to help.
I'll probably be closing this forum...well, not just closed, but it will go completely offline, at the end of January 2020.
