This is only occurring on Mac and only in OSX 10.12.

This is also a regression from 4.13

Right clicking in the dock, Show all windows, and selecting the game window does NOT fix the issue.

Running in -fullscreen does fix the issue

Standalone Game from within the editor DOES NOT have this issue.

This also affects packaged games on Mac

Steps to Reproduce
  1. Launch QAGame through the terminal using
    open --args QAGame.uproject -game -log

Result: Game window renders transparently
