Tested on Linux, MacOS, and Windows. On MacOS and Windows, we constrain the window's aspect ratio by adjusting the size when responding to resize events. On Linux, I've not found a way to do so, that doesn't result in fairly stuttery behavior and weird jumpy behavior of the resize handle, possibly depending on your window manager. So, black bars are displayed around the content. Maybe someone, at some point, finds a way. (SDL3 seems to have SDL_SetWindowAspectRatio) When the window is in fullscreen, black bars are display necessarily, of course, on all systems, unless the player GUI has exactly the same aspect ratio as the screen...
