With the latest beta version: 2017.1.0b1 (64bit)
I can’t use double click to focus on any GameObject, neither in Scene view, or in Hierarchy view.
For example, double click the “Main Camera” object in a newly created project, it shows this:

Then this:

And the Scene view didn’t focus onto the selected object.
Double click the object inside Scene view simply has no effect at all.
A little search on the internet tells me this might has something to do with GeForce Experience, sadly I don’t even have that installed.
This bug (I hope it’s a bug, not a behavior change) doesn’t exist in any of the previous version I use, including the “5.6.0 beta Mono Script Preview” version.
