Automatic reorientation of the viewport target to rotate around the centroid of the selected object seems to be broken.
To clarify, typically, orbiting any geometry will spin everything in the viewport except the white point in the center of gumball, now everything moves and it’s way disorienting.
I tried restoring defaults and cycling through the different camera, mouse, and interface options.
The disorientation makes this version frustratingly unusable. 
PS: if it diagnoses the problem any, I was able to roll back my settings back to a month old file, specifically importing the “view” options, and it works as expected now. ;s
