The problem here related to the fact that the RAID0 has two components of different sizes. A bug was introduced in Linux 3.14 which change the way data was laid out on those drives. So if you create such RAID0 with 3.13 (or earlier) and access it on 3.14 (or later) the data might get corrupted. We added code in Linux 5.4 so that array like that will be rejected (with error 524) unless they are explicitly marked to say which layout to use.

mdadm was also change to explicitly set a layout on newer kernels.

It seems that the new mdadm isn't being used here.

Coly: where are we up to with the new mdadm? Is it in Tumbleweed? If so, when did it land?

I just add the mdadm part to openSUSE:Base:System, it should be in Tumbleweed soon. Here is the changelog, - Create: add support for RAID0 layouts.
