From a sibling thread:

    EDIT: As far as I know, the best long-term answer here is for apps that present visuals full screen to "capture" the external display for exclusive use using an API (https://developer.apple.com/documentation/coregraphics/14562...), but that's not super common right now.
Sounds like it's totally possible for the software to have full control over the output if it wants to, this only affects software that runs in a "standard" fullscreen mode without explicitly taking full control over the output.

Yes, so you can go to the software vendor's "Ideas" or "Suggestions" page and ask for this, and post in forums asking people to upvote it, and hope the devs will do it. Not a great workaround. And sure, someone developed a script to get rid of this but no one is all that happy when Windows does something user-unfriendly that only a regedit hack will get rid of either.

Hence making every existing live visual software available on the mac redundant, unless the update and make this change.

It's not a complicated situation to grasp and it is seriously significant.
