Hi William,
Your finding could be explained by the fact that
https://jira.mariadb.org/browse/MDEV-34753 was fixed in MariaDB Server
11.4.4. In the 11.4.4 server error log, do you see any messages like
the following:
[Note] InnoDB: Memory pressure event freed ... pages
That's most definitely it. Some systems are subject to memory pressure, 
and I've never seen InnoDB adjust its buffer pool based on that, but I 
now gather that is actually intended behaviour.

Thanks for pointing me in the right direction!

Best regards,
Marko
