SHARE hyprland: Detect programs using XWayland

if w.xwayland then
hl.notification.create({ text = "Window uses XWayland: " .. w.title, timeout = 5000, icon = "warning" })
end
end)

sway version:

for_window [shell="xwayland"] title_format "<span background='#FFA0A0' foreground='#000000'>%title (%shell)</span>"
