You might want to try changing the texture download order in your app as
a workaround.

Calling pfuMakeSceneTexList then pfuDownloadTexList would change the
order on an Octane if you don't already call it. You'll also get better
TRAM useage on that platform.

This problem seems triggered by your specific circumstances and the
textures you load so most databases and users do not encounter it. As
Marcin explained, unfortunately the fix created more serious problems
which showed up under internal testing so the lesser of two evils was
chosen.

"One of the best-known folk theorems of software engineering is that
60% to 75% of conventional software projects are either never
completed or rejected by their intended users. If that range is
anywhere near true (and I've never met a manager of any experience
who disputes it) then more projects than not are being aimed at goals
which are either (a) not realistically attainable, or (b) just plain
wrong."
