Note like me if you were looking for the virtual keyboard output. You can overide window_set_input_text_callback or the default one shoots into Viewport::push_text_input which only works to push to the Control node with Key focus. So either make an invisible control with key focus or hook into one of those two options.

⚠️ Just a heads up that as of 4.5 stable, setting window_set_mode to WindowMode.WINDOW_MODE_MINIMIZED will not work on macOS if WINDOW_FLAG_BORDERLESS flag (or borderless property on the Window class) is set to true.

VSyncMode VSYNC_DISABLED
[...] Framerate is unlimited (regardless of Engine.max_fps).

Does that mean that we can't set a framerate limit when disabling vsync?

Very curious about this as well. Especially it's interaction with the OpenXR begin/wait/end frame code.

Engine.max_fps is obeyed regardless of V-Sync mode. It's just that with certain V-Sync modes, the FPS can't exceed the monitor refresh rate.

Of course, Engine.max_fps will work when V-Sync is disabled, as that's the most common scenario where it's used. The more contentious scenario is when V-Sync is enabled. Some engines disable their own FPS limiter when V-Sync is enabled through in-game means. This forces you to use an external FPS limiter or enable V-Sync at a driver level if you want to use both V-Sync and a FPS limit at the same time. Godot doesn't do this, so you can apply both V-Sync and a FPS limiter throrugh in-game means.

Engine.max_fps should work in XR scenarios as well, but I didn't test it.
