Here I have the same problem.
I guess it's something related to workspaces and plugins/scripts.
The plugin windows became unresponsive and something is happening and is broking down the Custom Workspaces.
Another issue is that when I prerender, no windows is showing up. From that moment, the entire interface behave like it would have a dialog box window open, but there isn't any.
When I click on tab, some of. them are getting focus, but not signaligt vissually that it does so.
Reveting back to 15.1 seem to work.
