Both gnome-shell animations paint their own independent static copy of
the desktop background on top of the live wallpaper actor: the
workspace-switch swipe (WorkspaceBackground) and the lock screen
(UnlockDialog, which already applies native blur). Patch both
private _createBackground methods to hide the static clone /
attach a shared-content actor so the live video shows through
instead, gated on the existing apply-to-lock-screen settings
