same problem:
1 year ago I tried opera gx and I had to uninstall it because it gave me several problems, today I wanted to try opera gx again to see if after 1 year it didn't continue giving me problems, at first everything was fine, but for some reason suddenly without touching anything twitch started to lag the image is stuck but the audio continues correctly, it doesn't matter what I do it doesn't solve it, there is no other program running or No games or anything at all, just Opera GX, I don't have any extensions installed either, I have almost everything disabled, I have also removed hardware acceleration and nothing. I don't understand why they sell this browser as the most optimized browser made for gamers if it fails more than the rest of the browsers, this browser has too many unnecessary things by default, and on top of that the 2 times I've tried it I spent a whole day configuring it so that it is as good as possible and suddenly it fails and you have to go back to your old browser. A year ago I went back to Chrome and today I tried Opera again and again many errors without a solution. I don't understand anything.
