Thanks for the response. Yep, done. I downloaded from kernel.org
6.04-pre1, and compiled it. I made certain only using those files.

With menu.c32, as per my example, reproducing here:

ui menu.c32

menu title Easy Boot Manager
default quirky
timeout 100

label quirky
menu label Easy 0.2.6
kernel vmlinuz
append root=/dev/sda3 rootwait rw

label Help
menu help help.msg

I still get the previous screen showing through on the background.
I have taken a couple of photos. The first is when I select the help,
and second when I hit Esc key and go back to the menu.

Note, this is booting on a 64-bit UEFI-firmware PC, in a esp fat32 partition.

Photos are here:
