Vertex Snapping Problem with 2019.3.0a2

Vertex snapping seems to be broken in 2019.3.0a2 (worked as expected in 2019.2.0b2). I can reproduce even with a new project. Create a cube and select it, select the move tool, hold the "V" key down and move the mouse to the vertices. The move gizmo will jump around randomly or not move at all. By chance it may actually select a vertex. Whether in perspective or iso mode doesn't make much difference. I spent hours playing with many scenarios but can't get it to work. I'm dead in the water on my project. Please help, Thanks.
