I am running Hyprland + Nvidia

The option in-game says its fullscreened when I open the game, however I still have to press my fullscreen keybind in my compositor for it to truly fullscreen. This is an issue because I forget to fullscreen sometimes and the windows does not tear, increasing latency.

Steps for reproducing this issue:

1. Startup CS2
2. See that the window is only maximized not truly fullscreen
3. Manually fullscreen each time on startup
