Image plane only works when attribute editor is open

[andy.lathamCJTQT]

I have a script that creates an image plane and imports an image sequence to it. However the sequence is stuck until I open Maya's attribute editor, at which point the sequence plays correctly.

Does anyone know why this happens? If it's a bug in Maya, is there anything I can put in my script to kickstart the sequence to work without requiring the user to open the attribute editor?

What version of Maya are you using?  I see this bugfix in the 2020.3 release notes which sounds like what you're seeing:

Image Plane created from script not updating without Attribute Editor open MAYA-105599

Ahh, I'm using 2018 currently. I know of someone who has had the issue in the last version of 2020 though.
