@cavvs said in enable-force-dark does not work:
This is not the behaviour observed in Chrome
I think Opera does its behavior on purpose where it has the additional force dark pages control that the flag depends and only-dark-theme behavior.
Have you ever refreshed a website using dark mode and seen short-lived white flashes
Yeah, most users call these flash bangs. There are lots of situations that these can happen. See https://issues.chromium.org/issues/40581308 for an example in Chrome. They're not always easy to fix. You're also not the only user to complain about them in Opera.
