OS version: 

  • Mac OS 10.9

Steps causing the bug to occur: 

  1. In System Preferences > Mission Control, uncheck the "Displays have separate Spaces" checkbox (which is checked by default)
  2. Create a composition with 2 or more windows
  3. Move each window to a separate space and make it fullscreen

How did the result differ from what you expected?: 

Expect to be able to make multiple windows fullscreen simultaneously on separate screens

Have you found a workaround?: 

Check the "Displays have separate Spaces" checkbox
