I am using arch inside a distrobox (podman) container on a fedora atomic system, however this shouldn't matter. I am using Hyprland and have not checked if this is reproducible on KDE. I suspect the issue may be unrelated to CS2 but compositor-related, but I am posting this here so it shows up on Google. It could also be a bug with using steam-native.

SDL_VIDEO_DRIVER=wayland fixes the issue and gives me lower input latency; however, my frame rate doesn't go above my monitor's refresh rate.

You have to comment out SDL_VIDEO_DRIVER=x11 from cs2.sh, the default on sdl3 is wayland so to switch back to x11 set your launch options to SDL_VIDEO_DRIVER=x11 %command%.
