@momijizukamori determined that this is most likely caused by a bad sorting in the recent_items query: https://github.com/dreamwidth/dw-free/blob/c8e8ae70f324c67b7794439f3706e8a7500740c4/cgi-bin/DW/Logic/LogItems.pm#L586 Should be ordered by jitemid desc instead of (or in addition to) journalid; otherwise entries in the same journal with identical timestamps won't be sorted consistently, which is what was happening in the community that reported the problem.
