Comment:
I just installed `Vulkan-Tools-1.3.231.1_1` just to test this, and: 

`export MANGOHUD=1`
`mangohud vkcube-wayland`

OUTPUT: 
`Cannot connect to wayland.`
`Exiting ...`

Given that `exec dbus-update-activation-environment DISPLAY XAUTHORITY WAYLAND_DISPLAY XDG_CURRENT_DESKTOP` is run after launching the `sway` WM, this cannot be pinpointed to a non-exorted $DISPLAY variable of sors. 

Based on limited evidence, I would be leaning upon a bug into `MangoHUD`, which is kinda of a shame, because version `MangoHud-0.7.2_1` fixed most of my problems with `MangoHUD` not working at all. 

Anyone else testing this, remember to check the manpages to understand why `export MANGOHUD=1` needs to be run. 

I will retest later with `MANGOHUD=1` added to `env` at login.
