@leocg I already said "Opera One by default"

I don't even know how to find GX or Air or whatever.

Opera 'one' or whatever is the linked product on both of opera.com's 'download now'

It would be nice if Opera could show its own internal buttons on a windows system with high contrast mode. Sample Picture:

You'll see how the toggles on the right simply don't show up, leaving the user to guess if a setting is enabled or not.

Steps to reproduce:
1 Fresh install of Windows 11 with High Contrast enabled
2 Opera.com and click download (downloads opera one by default)
3 Go into settings and scroll for a 'button' toggle and notice how you can't see them.

I can't find extensions that help for this either, and it is a big problem because certain websites will have the same issue (black background, black button outline, black toggle background, black button coloring, black checkmark internal to the button).
