Windows high contrast mode.

Hi to all.

I've been asked to research if windows high contrast mode, that is altered in the windows settings, touches off a specific WCAG success criterion? If something fails under windows high contrast mode conditions, is it a bug or a best practise?
Any research I've seen, states that if something fails when this feature is activated, it can fail against many different SC such as: 1.4.1, 1.4.3, 1.4.11, and 1.4.7.

Have you found that to be the case? Or have you come across any resources that say a specific success criterion covers it.

Any blogs, links or articles you've come across would be helpful here.

Thanks in advance.
Best wishes,

Brian Dalton.
