Btw. even the 3 seconds sounds awfully long. What platform is this and
which backend/renderer?

Did you pass some --with-cairo= option to Weston's configure?

Does the desktop fade in from black, or does it just jump out after 3
seconds?

Does it make a difference if you put

[shell]
startup-animation=none

in your weston.ini?

The 16 seconds delay happens because the application you replaced
weston-desktop-shell with does not do the job of weston-desktop-shell.
There is a 15 second timeout to show the desktop in case
weston-desktop-shell fails to signal ready.
