The laptops are on different Hyprland versions — system76 on 0.55.4,
the work laptop on 0.54.3 — and the option was removed in 0.55. Taking the
work laptop's config as canonical therefore introduced a config error on
system76 that did not exist before.
It is redundant either way: 0.54.3 reports the default as already enabled.
This is the first case of the shared config needing to tolerate two
compositor versions; it will not be the last.
