Something changed in settings and I'm not sure what happened. Whenever I open a model driven app in any solution in the environment, the tree menu on the left side is disappearing after refresh. See attached video, you can see the tree render then disappear. What setting needs to be adjusted?
During rendering I can see the menu for a moment....

Once its done rendering, it disappears, it's either underneath or pushed off to the side? I can't figure out how to get it back. Many of the options in the ribbon are also not appearing.
