Yes, that seems like a wireguard issue. Perhaps wireguard has problems
with multicast dst because it does not know which key to use? Just
guessing, i do not know wireguard.
Possible workaround would be to configure OSPF on that iface as ptmp and
specify neighbor address using 'neighbors' option. In such setting only
unicast is used.

Care to elaborate why? I do trust that you will know better.
'tick 2' will increase convergence time form ~1 sec to ~2 sec.
'rfc1583compat' is an obscure OSPF option for compatibility with ancient
RFC 1583 in some multi-area setups for the price of persistent routing
loops in some other multi-area setups. Completely irrelevant for
