How to turn off viewport to orthographic snapping during rotation on alt + middle mouse drag? That was view axis. Can be closed. 

Settings: I made factory reset and turned on emulate 3 button mouse.
Completely clean Blender without anything changed still has this
feature...

Issue: I want to turn off Blender behavior: Alt+ Middle mouse
button drag, which is causing the viewport to snap to front/top/left/right
orthographic view. I don't want this snapping feature.

And it seems it can't be turned off (Image 1) 3D View -> Rotate View -> View3D Rotate Modal, changing, disabling or clicking X doesn't change anything so it's maybe not this one setting  



Changing Rotate View - and picking Alt key (Image 2) changes normal rotation of viewport to Alt + middle mouse and this snapping feature to Alt + left mouse button (I'm using emulate 3 button mouse).
This is how I managed to solve it. Turn off View Axis.
