Ah, `fancy-splash-frame' checks `frame-visible-p', which, for my window
manager, depends on when I switch to the workspace.  So it's the removal
of the wait for visibility changes again (related to bugs #24091,
#25521, and #29095).  Although setting x-wait-for-event-timeout doesn't
seem to affect this, maybe that's a bug.

I guess for OP's case, the remote X display is just a bit slow, so the
frame doesn't become visible in time.
