RE: High quality resolution on Youtube is not available
Confirmed, replicated the issue, found the root cause and the workaround. Atleast for me... The ball is in Opera's team to decide if its actually an issue or not.
I didnt know it can fiddle with Youtube video quality too. In case this is an issue, Opera can look into it or maybe whitelist it or create some sort of exception. In case its not an issue but rather a functionality, user should get some sort of message or one time message so he can know what Battery saver can do in nut shell...
