Weird behavior: objects jump in the editor on simple move

[ClockworkOcean]

Hi!
I need help. When I move mesh or any other object in the scene it jumps. Looks like it’s trying to stick to some kind of invisible grid. But I have surface snapping turned off. Please, check the video below.
Also, I noticed that the jump happens at the moment when object and/or mouse cursor intersect another object.
It feels like I switched something on in the editor, but I don’t know what and how to turn it off.
Do you have any ideas what could it be?

I see someone got rid of this by binning the config/saved folder:
