Close down Opera and delete the "WidevineCdm" folder In the profile folder (see opera://about for the location), Start Opera and goto opera://components. You should see the version is 0. Click "check for update" and it should update. It may then say the same version as it said before, but this method gives you a fresh copy just in case something is wrong with it.
Thats looks great and if there is a way with keyboard short cut ( and mouse gesture option ) to switch this mode also switch back & forth would be great.
I understand it is now only manually switch my mouse from the menu which is little time consuming.....
And this problem also occured with disabled built-in ad-blocker and disabled all another extensions. But it occurs not every time I enter this page, I had to refresh this page multiple times and restart my browser mamy times. After few tries it has loocked on this page finally.
