Hi!, I had been using Opera a few months ago, but, I started experiencing a weird situation. The brigthness of the screen goes up an down witouth reason. I check, and its not a problem of my computer, because, usign other browsers or doing different activities the brightness is normal. I will be so glad if I could fix it. Thank you!!
