Selection tool moves objects in steps when using mouse
In CC2018 I could move my objects either in steps (arrows), big steps (Shift+arrows) or with precision using the mouse.
Now in CC2019 if I move something with the mouse it emulates the arrow keys movement, I'm talking about Twitch Badges (72x72 px) so It's a heavy issue for me, when working on big documents like 1080p this problem is barely noticeable
Most probably you have View > Snap to Grid option checked, or Snap to Pixel.
Please comment back if it still a problem.
