A flip packet delivered the queue's graphics end-of-pipe event after the work recorded before it. On the console a flip raises no such event: its interrupt context is always a typed token that the kernel routes to the display path (PS5 13.60 kernel), and neither Minecraft (PPSA17221) nor Death Stranding 2 (PPSA02015) sends a release that requests one. Death Stranding 2 registers the event before it fills its handler table, so the first flip's event reached a null handler (issue 6462). Minecraft did need it, but only because of when the flip hold ends. It writes its frame label after the flip in the same buffer and, after its next submission, waits on the event until that label is 1. The hold released the title at the flip packet, so it read the label before the worker had written it and slept until the flip event came. The hold now ends when the previous flip submission ran to its end and its recorded GPU work completed, so the label is in memory when the title reads it. The per-queue flip event latch is removed with the event: a queue's own release interrupts deliver as before.
