I'm running the latest dev builds, and at some point in the past month, toggling fullscreen mode has been broken. It attempts to enter fullscreen, but flickers my monitor and then ends up back at the desktop running in windowed mode. It doesn't matter if I render to main window or not, doesn't matter if I set it to fullscreen from the get go. Nothing I do gets it to work. I'm going to dig through the past few weeks of dev builds to see if anything stands out. Will report back soon.
