сrash on window resize due to excessive Wayland events

[LeynTheCat]

os: arch linux
kernel: 7.1.5-arch1-2
wm: hyprland 0.56.1 (wayland)

the engine crashes during window resizing under Wayland. Wayland sends too many resize events without throttling, and SDL2 attempts to process each event in real-time, leading to a segfault. The same issue is observed under X11.
