@joklok you are correct! white stripe appears even on full screen mode of web page.

i suppose to think, thats an opera for linux window manager using problem...
i dont use my linux for often needs, but its really stays annoying for me that white stripe! i think that if my laptop had a white design plastic, it souldnt be so annoying, but... it doesnt.
i dont like to think that i have to change my favourite browser for anything else, but my migration to linux stopped because of that white stripe.
its been a long time since i've posted my first message to this post... too much. its a pitty that we still dont have any comments on that glitch from developers...

@rollingpeanut would you be so kind to show some manual for this solution?

@hammersutd1983 nope youre on time its still there. You know it is so much time has passed... For a long of those years... My country is now struggling against russian aggression. It is has passed over 2 years, even bug tracker ticket got. But for over 2 years this bug is living in opera on linux. You know... Even my company, I'm working for, it is has banned opera. I'm tired of waiting for this bug to be solved.

@pindos i dont have such problem on my win 10 desktop and other windows devices

@argesever nope, that doesnt work for me. opera ver 78.0.4093.147

@d216 great job! thx!

@maximb yeap. We still have no any idea what is going on and why opera software don't care about this issue on linux.

@fulalas thats a really good question ))

@michaeldn i dont like dark mode neither. By the way, white strip shows up on all online video in full screen, not only on YouTube.

I'm on Manjaro 20.1 and Opera 70 and bug is still present. Dear devs, maybe its much faster to make that strip black in fullscreen?
