●○○○ — Not much; I'm just letting you know about it.
Steps causing the bug to occur:
Duration of a movie reported as 16s from "Get Movie Info" node.
When playing the movie the timestamp only reaches 13s.
I have a poor record calling things bugs, but I would be interested to know what is causing this if it isn't a bug.
I can't upload movies so I have put the movie in question here
OK, here's a clue. The icosahedron demo works on a machine with OS 10.15.7 (Catalina) but not on a machine with 11.2.3 (Big Sur).
Still looking ... but is it some security issue with application receiving keystrokes?
