Illustrator CC 2019 doesn't turn snapping off, no matter what.

Hi Doug, thanks for your reply.

I'm on Windows 10 Home (I have an Acer Nitro 5 laptop), but this is also happenning on my much beefier setup at home (64gigs of ram, Ryzen 7 CPU, etc.), which uses Win 10 Pro.

As for the example, it goes like this:

Whenever I try to move an object with precision, it ends up moving a lot more than just 1px, for example. It's like it's moving 10 pixels, even though I have all snapping turned off and pixel increment set to 1. To illustrate the example, here are some screenshots (not sure if it's gonna serve you any purpose, but it's better than nothing):

1) Let's say I'm trying to join those two red elements together. This is 2400% zoomed in, so a simple move of the mouse (I'm on a Logitech G502 which by itself has millimetric precision with the press of a button) or a press of the arrow keys would do the trick:

2) But whenever I do that, I get no precision at all. It snaps way far into the other object and never aligns to its edge, doesn't matter what I do. The result is as follow (this result was produced with a single press on the arrow key, with the lowest possible pixel increment):

The snapping is all over the place, as if it was skipping ten or more pixels at a time, never getting the exact precision I need, and every snapping option (again, the ones I'm aware of) is turned of. I'm almost 100% positive I'm not forgetting to uncheck/check any option, but a second opinion is always a good idea.

Was that enough to illustrate the problem? If not, let me know and I can try and be more clear.
