Could you at least tell us in the comments or log posts when you think the libffmpeg problem will be solved? I get tired of manually fixing things each time a new opera version appears when I could simply use chrome and not be bothered...
Don't turn it on, it's horrible for you sight. Got a light headache for 30 minutes due to putting it on for 10 seconds. I really don't like it. Please keep it on standard dark mode Opera GX
