  I nailed down that the echo (even of an empty string) has to be before
  "terminal_output gfxterm". Once it is after the "terminal_output
  gfxterm" instruction, the menu and background do not shows up.

There are no indications in the bug report that this bug was ever
reported to GRUB upstream or that a Debian maintainer of GRUB ever
reacted to it.

I am subscribed to grub-devel mailing list and do not remember to have
seen any discussion of "terminal_output gfxterm".
A search for these words does not yield many new messages.
One from 2018 might be related:
  https://www.mail-archive.com/grub-devel@gnu.org/msg26606.html
  "Instead of switching from "console" to "gfxterm", let's output to both.
   -terminal_output ${GRUB_TERMINAL_OUTPUT}
   +terminal_output --append ${GRUB_TERMINAL_OUTPUT}
  "
Maybe option --append has the same beneficial effect as echo before
terminal_output.

But bug-grub mailing list leads to a matching bug report of
21 Mar 2024:
  https://savannah.gnu.org/bugs/?65503
In 
  https://savannah.gnu.org/bugs/?65503#comment2
Michael Goffioul reports success with
  echo "Loading bootloader..."
  terminal_output gfxterm
No signs of GRUB developer attention, though.
Links lead to
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1110446
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1088356
  https://savannah.gnu.org/bugs/?67095


So the problem seems not to have the attention of developers or
maintainers but is well known among users.

If i were affected then i would write short, polite mails to
  grub-devel@gnu.org
  pkg-grub-devel@alioth-lists.debian.net
and ask for investigation of the mentioned respective bug reports
(3 for Debian, 2 for GRUB).


Have a nice day :)
