Hi Ondrej, it might be worth trying with that patch reverted, but I'm a bit confused at the commit message. That seems to imply my server didn't have a clean shutdown before upgrading to 10.3, which is possible but that upgrade is quite old by now (afaict it's between Stretch and Buster), so I'm unsure what to do now. innodb_fast_shutdown=0 doesn't terminate on 10.3.25, and I'm not sure if there are other ways to ensure a “clean shutdown”.
