in 4.11.2 I could open a new fp project template, build to windows, run that build it would play in windowed mode, then for VR I would hit Alt+Enter, everything worked fine by default.
in 4.12.1 I open a new fp project template, build to windows, when I run that build it is fullscreen, the for VR, Alt+Enter does not work.
How can I get my VR working again?
