Looks OK.

Looks OK but Firefox may not work if XDG_RUNTIME_DIR is on ZFS.

Obsolete since ports r528071.

Don't set these manually. Wayland compositor creates X11/Wayland sockets
for client applications to talk to. If hardcoded then applications may
launch on unintended server e.g., on Xorg instead of Sway.

Uncapped FPS is probably due to software renderer.
Does "glxinfo | fgrep -A11 Extended" show llvmpipe?

Can you check sway log why Xwayland failed to use device-specific
OpenGL driver? Make sure "sway -d" confirms Sway itself doesn't
fall back to llvmpipe.

Likely posix_fallocate issue. I can't reproduce that's why it takes eons
to fix.

Looks unrelated. To set locale define LANG in environ(7).

Probably related to software rendering in Xwayland or broken X11 socket.
