Comment:
This is currently documented in https://docs.voidlinux.org/config/graphical-session/wayland.html#video-drivers
I agree that the mesa drivers should be automatically installed by default, but adding them to `sway` is wrong. Instead, `libglvnd` should pull them in as default GL provider, but this is not so easy to achieve cleanly with current packaging situation
