I have done this but i have sites where i would like the function to work without the flickering.

I Really like Opera but i have not been able to resolve this. Some Websites in where javascript is active flicker, some cases really bad. Example would be http://www.nintendo.com/switch/. The sites red banner would flicker back and forth. if i disable javascript flickering stops with all affected sites but site doesn't load completely right. Any other browser they work ok. Any help would be appreciated prefer not to switch out of Opera
