I've done some research and read through this thread and I still have a question. I am a high school teacher. My students publish their games on Itch. None of the games will play in full screen mode even though it's enabled. We see the icon in the play screen, but clicking it does nothing. They are not complex games. If I check SharedArrayBuffer it launches to full screen. That seems like the perfect fix. The games are made in Godot 4.5 or 4.6. Earlier comments said ONLY enable it if you need it. How do I know if I need my students to do it? I don't want them to do it if it will break other parts of their games. So far on a test game it doesn't look like it breaks anything.
