Quite simply: Code changes that are 'as-designed' can occur at any time - even in conjunction with the only most recent version. The code changes that cause this warning dialog to appear are new to version 11.5 so it would have not been possible for it to show in previous versions.

It isn't a bug. Meaning, it is behaving currently as-designed. There is an active feature request to have a "Do not show this again" check box for those of you who don't disable your integrated GPU via BIOS.
