Exclusive Fullscreen? No
Borderless Fullscreen mode? No
Telling your wm to just render it raccross the entire display with no decorations? Yes

Benefits of this approach are of raccourse that the application expects being resized and also moved around and also not being in the foreground

@charlotte isn't borderless fullscreen literally the same as the last option

@saphire not really because applications know when they are in borderless fullscreen mode
