Display Manager question

[David]

Last week, I replaced the file "default.png" in my background directory,
and was delightfully enjoying a new custom backsplash, instead of the new
fancy
one that Fedora has ( light color blue with some rectangular glass cluster
).

In my recent update yesterday, something replaced my custom backsplash
with the old default.png.

Why would an update do that ?

This is the kind of stuff you can expect from living in Rawhide, so
I am NOT complaining.       And I am using Xfce, so the DM
is LightDM, specifically,

lightdm-1.30.0-8.fc32 ( Rawhide's current version, if using Xfce )

P.S.

It would be nice if distros offered an easier way to customize the login
backsplash.
