The problem doesn't come from the casper package. The problem is in the
grub-efi-amd64-bin package (latest version tested:2.04-1ubuntu16).
Actually, it's the file grubx64.efi inside this package
(/usr/lib/grub/x86_64-efi/monolithic/grubx64.efi).

Have a look in casper on the xubuntu ISO.
Confirm your menuentry uses the same as ISO:

Oops, After a little more experimenting, it appears that it is the version of

To clarify, if I install mkusb in 18.04 the USBs it makes boot with grub 2.02.
If I install mkusb in 19.10 the USBs it makes boot with grub 2.04.
Grub 2.02 boots ISOs, grub 2.04 does not boot ISOs.

mkusb can boot from grub 2.04 when pointing to a partition, into which

Perhaps the cause is a secondary library or dependency that iso9660.mod is
